Answer:
x=9
Step-by-step explanation:
subtract 22 from both sides, simplify 3x = 10x-63, subtract 10x from both sides of the equation, simplify -7x = -63, divide both sides of the equation by the same factor -7x/-7 = -63/-7, then simplify
The value of the variable 'x' is 9. Then the length of the side QR will be 49 units.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The ratio of the matching sides will remain constant if two triangles are comparable to one another.
The triangles ΔQPR and ΔQRS are congruent triangles. Then the corresponding sides will be equal. Then the equation is given as,
PQ = QR
3x + 22 = 10x - 41
Simplify the equation, then we have
10x - 41 = 3x + 22
10x - 3x = 22 + 41
7x = 63
x = 63 / 7
x = 9
The length of the side QR is given as,
QP = 10 (9) - 41
QP = 90 - 41
QP = 49
The value of the variable 'x' is 9. Then the length of the side QR will be 49 units.

late fee of $5.75 per day. She realizes that she will not be paid until 10 days from
now. What will the balance of the account equal on the 10th day? Show your work.
the balance in the account at the 10th day will be equal to - $ 57.5.
Late fee for 1 day = $ 5.75
Number of days = 10
We will calculate the late fees for 10 days by using the operation of multiplication.
So, late fee will be:
Late fees = 10 × $ 5.75
Late fees = $ 57.5
Balance in the account at the 10th day = 0 - Late fees
Balance in the account at the 10th day = 0 - $ 57.5
Balance in the account at the 10th day = - $ 57.5
Therefore, the balance in the account at the 10th day will be equal to - $ 57.5.

ind the equation of the line tangent to the graph of the given function at the point with the indicated x-coordinate.
f(x) = (x0.5 + 5)(x2 + x); x = 1
The equation of the line tangent to the curve is y = 19 · x - 7.
How to determine the equation of the line tangent to a curveIn this problem we need to find the equation of a line tangent to the function f(x) = (√x + 5) · (x² + x) for x = 1, that is, a line that only passes through one point of the entire curve. The equation of the line is introduced below:
y = m · x + b
Where:
m - Slopeb - InterceptThe slope of the line can be found by evaluating the first derivative of f(x) for x = 1:
f'(x) = (1 / 2√x) · (x² + x) + (√x + 5) · (2 · x + 1)
f'(1) = (1 / 2) · 2 + 6 · 3
f'(1) = 1 + 18
f'(1) = 19
The y-coordinate of the curve is:
f(1) = (√1 + 5) · (1² + 1)
f(1) = 6 · 2
f(1) = 12
Lastly, we determine the intercept of the tangent line:
b = y - m · x
b = 12 - 19 · 1
b = - 7
The equation of the line tangent to the curve is y = 19 · x - 7.

Answer:
The transformation that map line RS to line R"S" is " rotation of 180° about the origin, followed by a translation (x, y) → (x + 1, y + 1)" ⇒ B
Step-by-step explanation:
Let us revise some transformationIf the point (x, y) rotated about the origin by angle 180° counterclockwise, then its image is (-x, -y) ⇒ R(180, O) (x, y) → (-x, -y) If the point (x, y) translated horizontally to the right by h units then its image is (x + h, y) ⇒ T (x, y) → (x + h, y)If the point (x, y) translated vertically up by k units then its image is (x, y + k) ⇒ T (x, y) → (x, y + k)∵ The coordinates of the point R = (-2, 4)∵ The coordinates of point R" = (3, -3)→ Both coordinates in R" have opposite signs then R∴ R rotated 180° about the origin ⇒ using the 1st rule above∴ R' = (2, -4)→ Find the difference between the x-coordinate of R" and x-coordinate of R'∵ xR" - xR' = 3 - 2 = 1→ By using the 2nd rule above∴ R' translated 1 unit to the right → Find the difference between the y-coordinate of R" and y-coordinate of R'∵ yR" - yR' = -3 - (-4) = -3 + 4 = 1→ By using the 3rd rule above∴ R' translated 1 unit up∴ The rule of translation is T(x, y) ⇒ (x + 1, y + 1)Let us use these 2 rules on S to find S"∵ The coordinates of the point S = (-4, -1)∵ S is rotated 180° around the origin→ By using the 1st rule above, opposite the signs of its coordinates∴ S' = (4, 1)∵ S' translated 1 unit right→ By using the 2nd rule above, add its x-coordinate by 1∵ S' translated 1 unit up→ By using the 3rd rule above, add its y-coordinate by 1∴ S" = (4 + 1, 1 + 1)∴ S" = (5,2)→ That means the rules of transformation of point R is rightThe transformation that map line RS to line R"S" is " rotation of 180° about the origin, followed by a translation (x, y) → (x + 1, y + 1)"

Answer:
13.94 seconds
Step-by-step explanation:
The greatest number with 2 decimal places that can be rounded to 13.9 is 13.94.
Answer: 13.94 seconds
The announcer said that Ingrid has won the race in 13.9 seconds, then the slowest time she could have run is 13.94 seconds.
What is approximation?Something similar to something else but not precisely the same is called an approximation. By rounding, a number can be roughly estimated.
By rounding the values in a computation before carrying out the procedures, an estimated result can be obtained.
13.94 is the largest number that can be rounded to the nearest two decimal places and be equal to 13.9.
Because after the second decimal, that is 4 the number has to increase as per the rules of approximation. That's why the number 13.94 up to two decimal places is correct.

If 2 < a < 5 and 1 < b < 2 find all possible expressions a+b,ab,a-b,and a/b
The range of values for the expressions are given by these following compound inequalities:
3 < a + b < 7.2 < ab < 10.0 < a - b < 4.1 < a/b < 5.What is a compound inequality?A compound inequality is a combination of multiple inequalities, at least two, involving operations such as and and or, explained below.
The and operation between multiple sets is composed by the elements that belong to all the sets.The or operation between multiple sets is composed by the elements that belong to at least one of the sets.Hence one example of a compound inequality is:
a ≤ x ≤ b.
Which is read as follows:
x is greater or equal than a and less or equal than b.
What is the range of the addition?The smallest possible value is when both a and b are at their lower bounds, hence:
a + b = 2 + 1 = 3.
The greatest possible value is when both a and b are at their upper bounds, hence:
5 + 2 = 7.
Then the range is:
3 < a + b < 7.
Since the ranges of a and b are open intervals, the ranges of the operations will also be composed by open intervals.
What is the range of the multiplication?The smallest possible value is when both a and b are at their lower bounds, hence:
a x b = 2 x 1 = 2.
The greatest possible value is when both a and b are at their upper bounds, hence:
a x b = 5 x 2 = 10
Then the range is:
2 < ab < 10.
What is the range of the subtraction?The smallest possible value is when a is at it's lower bound and b is at it's upper bound, hence:
2 - 2 = 0
The greatest possible value is when a is at it's upper bound and b is at it's lower bound, hence:
5 - 1 = 4.
Hence the range is:
0 < a - b < 4.
What is the range of the division?The smallest possible value is when a is at it's lower bound and b is at it's upper bound, hence:
2/2 = 1.
The greatest possible value is when a is at it's upper bound and b is at it's lower bound, hence:
5/1 = 5.

Cory graphed y = 100 - 50x x to represent the percentage of battery life

Percentage of battery life remaining
A. 0≤x≤ 100
Remaining Battery Life
100
Time (hours)
hr
The reasonable domain of the given situation is 0≤ x ≤2 that is 0 to 2 hours.
We see that x is represented as the number of phone hours used, therefore it has to be a number larger or equal to zero, but not a negative number. So, on one end we have that the number of phone hours used (x) must be larger or equal to zero. On the other hand, when the battery goes to zero, there are no more phone hours to use. We can find what is that other limit by making the battery percent (y variable) equal to zero, and solve the equation for x, thus giving us the upper limit of usable phone hours:
=> y = 0 = 100 - 50x
=> 100 = 50x
=> x = 100/50
=> x = 2
Therefore, the phone can be used for a maximum of 2 hours and the situation may be written as 0≤ x ≤2.

A strategy for teaching division is by repeated subtraction. It involves repeatedly subtracting the same integer from a big number until the result is zero. It is a fantastic approach to teach kids about division. A technique called repeated subtraction, commonly referred to as division, removes an equal amount of items from a group.
Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.

The difference between 4 and the sum of a number and is equal to twice that number.
Repeated subtraction is a method for teaching division. Until the result is zero, the same integer must be repeatedly subtracted from a large number. Repeated subtraction, sometimes known as division, is a method that takes an equal number of elements out of a group.
Division's opposite is multiplication. If 3 groups of 4 total up to 12, then 4 are in each group when 12 is divided into 3 equal groups. The fundamental goal of division is to produce equal groups or to determine how many individuals are in each group following a fair distribution.

T
R
v (2x+15)
(2x + 5)°
Answer:
95°
Step-by-step explanation:
You want the measure of angle TVZ, when adjacent angle (2x+5)° and its supplement (2x+15)° are given. The larger of these is a vertical angle with respect to TVZ.
Linear pairThe angles marked (2x+15)° and (2x+5)° are a linear pair, hence supplementary.
((2x+15)° +(2x+5)° = 180°
4x +20 = 180 . . . . simplify
x +5 = 45 . . . . . . . divide by 4
x = 40 . . . . . subtract 5
Angle TVZ is a vertical angle with respect to the one marked (2x+15)°, so has the same measure:
∠TVZ = (2(40)+15)°
∠TVZ = 95°
__
Alternate solution
The two angles RVW (2x+15)° and ZVW (2x+5)° obviously differ by 10°. They are a linear pair, so their sum is 180°. Finding these angles is then a "sum and difference" problem. The larger of the solutions is the one we want, as (2x+15)° is a vertical angle to TVZ. We know the larger of the solutions to the sum and difference problem will be (180° +10°)/2 = 95°, the measure of TVZ.
More about sum and difference problems:
When a+b = s, and a-b = d, the larger value (a) can be found by adding these equations: (a+b) +(a-b) = s+d, or 2a = s+d, or a = (s+d)/2. This is the expression we used above to find the larger of the two angles. (You notice it is not necessary to solve for x.)

Marvin Co. sells pens ($6) and flashlights ($10). If total sales were $624 and customers bought 7 times as many pens as flashlights, what would be the number of pens sold?
Marvin Co. sells a total of 12 flashlights and 84 pens
Price of pen sold by Marvin Co. = $6
Price of flashlight sold by Marvin Co. = $10
Total sales = $624
Let the number of flashlights be x and the number of pens be y
Formulating the equations:
10x + 6y = 624
It is given that customer bought 7 times as many pens as flashlights, therefore:
y = 7x
Putting y = 7x in the equation we get,
10x + 6(7x) = 624
