How do I complete this formal check?
Answers
Answer:
Step-by-step explanation:
The first two steps are for the purpose of eliminating fractions. Doing so results in 4(2x - 5) = 9(x - 2), which is to be solved for x.
Perform the indicated multiplication, obtaining:
8x - 20 = 9x - 18.
Then combine like terms: -2 = x, or
x = -2.
To complete the formal check, substitute -2 for x in the first equation. This results in:
(1/3)(-4 - 5) = (3/4)(-2 -2), or
-3 = -3
... which is obviously true.
Which diagram represents a line of symmetry for the regular pentagon?
Answers
The correct answer is Pentagon 2 or B
Explanation:
In mathematics and related disciplines, a line of symmetry is a line that divides a figure, for example, a triangle, circle, or pentagon into two symmetrical or equal sides. This means you can fold the image following the line and both sides will be identical. This occurs in the second pentagon because the line that begins in the top of the figure divides it into two equal sides. Indeed each of the sides includes half of the base and two angles that coincide if you fold the figure following line.
Answer:
its b

Sam is eating a Big Hamburger. The first bite was 20% of the Hamburger, the second bite was 20% of what is left and so every next bite is 20% of what is left. How much did the Hamburger weigh originally, if after the second bite there was 160g of it left?
Answers
Answer:
250 g
Step-by-step explanation:
160 g after two bites
80% after 1 bite
[tex]\frac{80}{100} =.8[/tex]
160 ÷ .8=200
200 ÷ .8=250
Answer:
250
Step-by-step explanation:
We start with the 100% and if we take 20% from that we get 80% if we take 20% from that we have 64%. This means 160 is 64%. So if we do 160/64*100 we will get the answer!

if a+b=7, and a2+b2 =25 then an=?
Answers
Answer:
Solution set: (3, 4) and (4, 3)
Step-by-step explanation:
Please, to indicate exponentiation, use " ^ ": a^2 and b^2
Then you have:
a + b = 7 and a^2 + b^2 = 25.
Let's eliminate b: Solve a + b = 7 for b, obtaining b = 7 - a.
Then we have:
a^2 + (7 - a)^2 = 25, or
a^2 + 49 - 14a + a^2 - 25 = 0, or
2a^2 - 14a + 24 = 0, or
a^2 - 7a + 12 = 0, which factors as follows:
(a - 3)(a - 4) = 0
This results in a = 3 and a = 4, in which case the equation a + b = 7 tells us that the b values are 4 and 3 respectively.
Solution set: (3, 4) and (4, 3)

Bernard is one and half times old as Henry six years ago he was twice as old as Henry how old are the boys now
Answers
Answer:
Henry=12, Bernard=18
Step-by-step explanation:
let Henry's age = x
let Bernard's age= 1.5x
according to d passage 6yrs ago x×2=1.5x
mathematically that is (x-6)2=1.5x-6
2x-12=1.5x-6
2x-1.5x=-6+12
0.5x=6
divide both sides by the co-efficient of x which is 0.5 can also be written as ½
there fore x=6÷½
x=Henry's age=12years
1.5x=Bernard's age=12×1.5=18years
Answer fast pleaseee, Solve the following system of equations: y= -5x +1 and y= -x-3
Answers
Answer:
x=1 y=-4
Step-by-step explanation:
Answer:
(1, - 4 )
Step-by-step explanation:
Given the 2 equations
y = - 5x + 1 → (1)
y = - x - 3 → (2)
Since both are expressed in terms of y, equate the right sides, that is
- x - 3 = - 5x + 1 ( add 5x to both sides )
4x - 3 = 1 ( add 3 to both sides )
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into (2)
y = - 1 - 3 = - 4
Solution is (1, - 4 )

if f(x)=x+7and g(x)=1/x-13, what is the domain of (f•g)(x)
Answers
Answer: 7x-90/x-13
Step-by-step explanation:
f(x)= x+7
g(x)=1/x-13
(f•g)(x)=1/x+13+7
1+7(x-13)/x-13
1+7x-91/x-13
7x-90/x-13
Answer:
(-∞, 0)∪(0, ∞)
Step-by-step explanation:
You are given the functions f(x) and g(x). Now, you have to find (f*g)(x). To do this, you have to multiply the two functions.
f(x) = x + 7
g(x) = 1/x - 13
(f*g)(x) = (x + 7)(1/x - 13)
(f*g)(x) = -13x + 7/x + 1 - 91
(f*g)(x) = -13x + 7/x - 90
The domain has to include all of the x-values that will produce a rational number. So, look at where the x's are locate
-13x: You could put any rational number into this value and still have a rational number.
7/x: For this value, you cannot have 0 as an x-value. Every other number is fine.
This means that the domain will be (-∞, 0)∪(0, ∞).
You use parentheses and not brackets for the zero side because you don't want to include zero in the domain, but you do want to include all of the other numbers around zero. There are no brackets on the infinity side because infinity isn't a number. The ∪ symbol is used to combine domains.

2x+24=144
2x=144-24=120
x=120/2=60
Hope this helps!
Step-by-step explanation:
Therefore,
2x+24= 144° [ Vertically positive angles]
Or, 2x= 144-24
Or, 2x= 120
Or, x= 120/2
Therefore, x= 60°

Yuri is thinking of a 4-digit whole number. He rounds his number to the nearest thousand. His answer is 4000, what is the smallest number yuri could be thinking of?
Answers
Answer:
Smallest number = 3500
Step-by-step explanation:
Rounding of numbers involve replacing numbers with simpler numbers. In order to round a number to the nearest thousand, the last 3 digits of the number should be considered. If the last 3 digits are less than 500, the number is rounded down(the thousand figure is unaffected), but if the last 3 digits are greater or equal to 500, the number is rounded up.
In this case, Yuri is thinking of a 4-digit whole number and he rounds his number to the nearest thousand. Since his answer is 4000, the smallest number yuri could be thinking of would be 3500 and the highest number he could be thinking of is 4499.
Thus, the smallest number Yuri could be thinking of is 3500

The angle congruent to ∠ACB is B. ∠AED.
What are congruent angles?Congruent angles are the angles that have equal measure. So all the angles that have equal measure will be called congruent angles.
Congruent Angles have the same angle (in degrees or radians).
Now from the given figure,
In triangle ABC and triangle AED

. (10 points) Based on pre-trial speculation, the probability that a jury returns a guilty verdict in a certain high-profile murder case is thought to be 15% if the defense can discredit the police department, and 80% if they cannot. Veteran court observers believe that the skilled defense attorneys have a 70% chance of convincing the jury that the police either contaminated or planted some evidence. What is the probabiliy that the jury returns a guilty verdict?
Answers
Answer:
34.5% probability that the jury returns a guilty verdict
Step-by-step explanation:
We have these following probabilities:
If the police can discredit the police department, 15% probability of a guilty verdict.
70% probability of the police department being discredited by the defense.
If the police can discredit the police department, 80% probability of a guilty verdict.
100 - 70 = 30% probability of the defense not discrediting the police.
What is the probability that the jury returns a guilty verdict?
15% of 70% and 80% of 30%. So
p = 0.15*0.7 + 0.8*0.3 = 0.345
34.5% probability that the jury returns a guilty verdict

if f(x) =5x-2 and g(x) = 2x +1 find(f+g)(x)
Answers
Answer & Step-by-step explanation:
When we see (f + g)(x), it means that we are going to be adding f(x) to g(x).
f(x) = 5x - 2
g(x) = 2x + 1
(f + g)(x) = (5x - 2) + (2x + 1)
Combine like terms.
(f + g)(x) = 7x - 1
So, (f + g)(x) equals 7x - 1
I need help finding the surface area, can someone help
Answers
Answer:
1). Surface area of the prism = 112 cm²
2). Area of the sphere = 615.8 cm²
Step-by-step explanation:
1). Surface area of the triangular prism = Area of the triangular bases + Area of three lateral (rectangular) sides
Area of a triangular base = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(3)(7)[/tex]
= 10.5 cm²
Area of a rectangle = Length × width
Area of the rectangular lateral sides = (3 × 5) + (8 × 5) + (7 × 5)
= 15 + 40 + 35
= 90 cm²
Surface area of the prism = (2 × 10.5) + 90
= 21 + 90
= 112 cm²
2). Surface area of the sphere = 4πr²
= 4π(7)²
= 615.75
≈ 615.8 cm²
