help! I only have a certain amount of time.... easy points! The sum of 3 times a number and 4 is 13. Find the number.
Answer:
The number is 3
Step-by-step explanation:
Ok, first thing's first: we need to make the words into an actual equation.
since it just says a number I'll use x
3 times x + 4 = 13
3x +4 =13
Now that we have our equation, we can solve for x
3x + 4 = 13
-4 -4
3x = 9
I subtracted 4 on both sides to get rid of the 4 and move it to the other side of the equation, so we can try to get x by itself.
3x =9
/3 /3
x = 3
I divided both sides by 3 to get rid of the 3 that's being multiplied by x
Now we have our number : x = 3
I hope this helps :)
If m2 = 9x + 7 and m3 = 5x + 5, what is m1?
Answer:
B
Step-by-step explanation:
∠ 2 and ∠ 3 are a linear pair and sum to 180°
∠ 2 + ∠ 3 = 180 , that is
9x + 7 + 5x + 5 = 180
14x + 12 = 180 ( subtract 12 from both sides )
14x = 168 ( divide both sides by 14 )
x = 12
Then
∠ 3 = 5x + 5 = 5(12) + 5 = 60 + 5 = 65°
∠ 3 and ∠ 1 are vertically opposite angles and are congruent , so
∠ 1 = 65°

|5k-8| / 10 = 2
|5k-8| / 10 is a fraction btw
Answer:
K is -12/5
k is also 28/5
Step-by-step explanation:
Here, we want to solve the equation
|5k-8| = 10(2)
5k-8 = 20
5k = 20 + 8
5k = 28
k = 28/5
or
5k-8 = -20
5k = -20 + 8
5k = -12
k = -12/5

The two triangles are symmetrically the same the only difference is they are opposite Intersecting at C.
Angle DCE and BCA intersect from the triangles which both form a similar angle let's assume are 60 degrees.
Therefore, Angle ACE and BCD are 120 degrees.
Therefore all sides from both triangles correspond to be both equal, for example, BA = ED, AC = DC, BC = EC
C is the midpoint of AD and BE therefore AC = CD and BC = CE.
The angles too are equally corresponding such as,
Angle ABC = DEC , CAB = CDE and BCA = ECD

A forest fire leaves behind an area of grass burned in an expanding circular pattern. If the radius of the circle of burning grass is increasing with time according
to the formula r(t) = 5t + 2, express the area A burned as a function of time, t (minutes).
The area A burned as a function of time, t is
A(t)=78.5t²+62.8t+12.56
What is Radius of the circle?A circle's or sphere's radius is any of the line segments that connect the object's center to its perimeter; in more recent usage, it is also their length.
According to the given values ;
r(t)=5t+2
.°. A(t)=πr²=π*(5t+2)²
=π(25t²+20t+4)
= 78.5t²+62.8t+12.56

hi guys can u please help and doing hw and i don't understand.
Answer:
C
Step-by-step explanation:
The weight of the weight lighting bar = the initial value/y-intercept (b) = 45
Amount of weight = x
Total amount of weight = y
The rate of change (m) = 1
Thus to write the function that models this situation, substitute m = 1, and b = 45 into y = mx + b
Thus:
y = (1)x + 45
y = x + 45

Debbie has at most $58 to spend on clothes. She wants to buy a pair of jeans for $22 and spend the rest on t-shirts. Each t-shirt cost $9. Write and solve an inequality that represents this word problem.
Answer:
The Inequality Equation =
22 + 9x ≤ 58
The number of T -shirts Debbie can buy is at most 4 T-shirts
Step-by-step explanation:
Let the number of T shirts Debbie can buy be represented as x
We are told in the question: Debbie has at most $58 to spend on clothes.
This means she would not exceed $58. She would be spending less than or equal to $58
The Inequality Equation =
$22 + $9 × x ≤ $58
22 + 9x ≤ 58
Solving the Inequality Equation above:
22 + 9x ≤ 58
9x ≤ 58 - 22
9x ≤ 36
x ≤ 36/9
x ≤ 4 shirts
The number of T -shirts Debbie can buy is at most 4 T-shirts

Answer:
acute scalene triangle
Step-by-step explanation:
The largest angle is acute, and all sides are different lengths. The triangle is an acute scalene triangle.
____
The magnitudes of the coordinate differences are ...
WX = (7, 5), XY = (2, 7), WY = (9, 2)
The two sides that are closest in length are ...
WX = √(49+25) = √74
WY = √(81 +4) = √85
Obviously, these are different lengths.
You can get a clue by comparing the numbers whose squares you are adding:
7^2 +5^2 > 7^2 +2^2 . . . . . WX > XY
9^2 +2^2 > 7^2 +2^2 . . . . WY > XY
so, the only question is relation between WX and WY. We note that the length of WX is less than one of the coordinate differences of WY, so we know WY is the longest. (√74 < 9)
We can tell from the graph that angle X (opposite longest side WY) is an acute angle, so the triangle is acute.

the sum of two numbers 94. their diffirence is 12
Lets denote the numbers x and y:
The sum of two numbers 94 → x + y = 94
Their difference is 12 → x - y = 12
We have:
x + y = 94
x - y = 12
---------------- Add both equations
2x = 106
x = 106/2
x = 53
Using first equation:
x + y = 94
53 + y = 94
y = 94 - 53
y = 41
A/ The numbers are 53 and 41.

What is a geometric sequence?There are three parameters which differentiate between which geometric sequence we're talking about.
The first parameter is the initial value of the sequence.
The second parameter is the quantity by which we multiply previous term to get the next term.
a) The common difference is;
-8 - 1 = -9
b) The common difference is;
-9 - 1 = -10
c) The common difference is;
-10 - 1 = -11
a2 = 16 * 3/2 = 24
a3 = 24 * 3/2 = 36
a4 = 36 * 3/2 = 54
Therefore, the next terms are;
f(2) = 5 * -2 = -10
f(3) = -10 * -2 = 20
f(4) = 20 * -2 = -40

in a right triangle, the side c opposite the right angle is called the hypotenuse, and the other two sides a and b are called legs. the pythagorean theorem states that in any right triangle, the lengths of the three sides are related by the equation . use the pythagorean theorem to answer the following question. determine the length of the hypotenuse in a right triangle with legs 5 inches and 12 inches. a. approximately 13.38 inches b. 13 inches c. 169 inches d. 17 inches
The length of the hypotenuse is 13.
A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
According to the question ,
Given that , legs is 5 inches and 12 inches
how to find hypotenuse :
we know , c^{2} = a^{2} + b^{2}
⇒ c^{2}= 5^{2} + 12^{2}
⇒ c^{2} = 25 + 144
⇒ c = \sqrt{169}
⇒ c = 13
The length of the hypotenuse is 13.
Correct option is (b) 13 inches .

2(9n-1)+7(n+6)=-60
what is this answer
Answer:
n=-4
Step-by-step explanation:
2 (9n-1)+7(n+6)= -60
18n-2 +7n + 42 = -60
25n + 40 = -60
25n = -100
n = -4
Answer:
n = - 4
Step-by-step explanation:
2 ( 9n - 1 ) + 7 ( n + 6 ) = - 60
Solve the brackets.
18n - 2 + 7n + 42 = - 60
Combine like terms.
25n + 40 = - 60
Subtract 40 from both sides.
25n = - 60 - 40
25n = - 100
Subtract 25 from both sides.
n = -4
