Answer:
C . 4
Step-by-step explanation:
step 1 : -3 multiply with inside of the ( 7x-5 )
= -21x + 15
step 2 : then it will be 21x + 15 = 87 + 3x
step 3 : switch between the odds into like this
21x - 3x = 87 - 15
step 4 : subtract it all
18x = 72
step 5 : bring 18 to the other side
x = 72/18
step 6 : to find the ans of x is just calculate them
x = 72 ÷ 18
= 4
Or you can do like these ⬇️
-3 ( 7x - 15 ) = 87 + 3x
21x + 15 = 87 + 3x
21x - 3x = 87 - 15
18x = 72
x = 72/18 or 72÷18
x = 4
A cone with a volume of 1152π cubic meters has a radius of 12 meters. Which of these statements is correct?
Select one:
Its height is two thirds the length of its radius.
The length of its radius is twice its height.
The length of its radius is two thirds its height.
Its height is twice the length of its radius.
Answer:
Step-by-step explanation:
B
Answer: it’s hight is twice the length of its radius
Step-by-step explanation:
2. The volume of a cylinder varies jointly with its height and the square of the radius. A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. Another spice container is 3 inches tall with a radius of 1.5 inches, what would be the volume?
Answer:
Volume=21.195 cubic inch
Step-by-step explanation:
The volume of a cylinder varies jointly with its height and the square of the radius is expressed as
V∝hr^2
Introducing our constant of proportionality,K we have that
V =Khr^2
Given that A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. We have that
V =Khr^2
7.85=K 2.5 X 1^2
K=7.85/2.5 x1
K=3.14
Given that another spice container is 3 inches tall with a radius of 1.5 inches, Volume=?
V =Khr^2
V=3.14 X 3 X 1.5^2
V=21.195 cubic inch

Hal read 114 pages of his book during vacation. This was 60 percent of the book. How many pages does Hal have left to read
Answer:
76
Step-by-step explanation:
Let number of pages=x
60% of x=114
x=114×100/60=190
pages left=190-114=76
The probability of rolling a number cube and getting a 6 and 3.
We have to find out the probability of getting 6 and 3,
Since this only one roll it is not possible to get 2 numbers in one roll
So, I will presume you want the probability of getting 6 or 3,
Total number of outcomes= {1,2,3,4,5,6} = 6 outcomes
Number of favorable outcomes = {3,6} = 2 outcomes
Probability of rolling 6 or 3 = [tex]\frac{Number'of 'favorable' outcomes}{Total' number 'of' outcomes}[/tex]
= 2/6
= 1/3 or 0.33333%
Therefore the probability of rolling 6 or 3 is one in three chances

Are the equations m + 3 = -5 and m = -2 equivalent? Explain why or why not?
Answer:
Step-by-step explanation:
When m+3=-5, collection of like terms says; -5-3
Now,-5+-3 = -8 and -2≠-8 hence,they aren't equivalent

Mr. Carlevato and Mr. Burrows get into a debate about two different expressions. · Mr. Carlevato says "2(2x + 3) is equal to 4x + 6". · Mr. Burrows says "Nope, wrong, those are clearly different expressions" Try substituting x=5 into both expressions. Do you get the same answer for both expressions? Show your work!
Answer:
Yes, the same answer is obtained.
Step-by-step explanation:
According to Mr. Carlevato, [tex]2(2x+3)[/tex] is equal to [tex]4x+6[/tex]. However, [tex]2(2x+3)[/tex] is not equal to [tex]4x+6[/tex] according to Mr. Burrows.
Put [tex]x=5[/tex] in [tex]2(2x+3)[/tex]
[tex]2[2(5)+3]=2(10+3)=2(13)=26[/tex]
Put [tex]x=5[/tex] in [tex]4x+6[/tex]
[tex]4x+6=4(5)+6=20+6=26[/tex]
Therefore,
[tex]2(2x+3)=4x+6[/tex]
Yes, the same answer is obtained.

1. (08.01, 8.02 MC) An expression is shown below: 2x3y2 + 18xy2 − 20x2y − 180y Part A: Rewrite the expression so that the GCF is factored completely. (4 points) Part B: Rewrite the expression completely factored. Show the steps of your work. (6 points) (10 points)
Answer:
A. 2y
B. (xy − 10)(2x²y + 18y)
Step-by-step explanation:
Part A: Rewrite the expression so that the GCF is factored completely.
2x³y² + 18xy² − 20x²y − 180y
Factoring y out, we have
(2x³y + 18xy − 20x² − 180)y
Factoring 2 out, we have
(x³y + 9xy − 10x² − 90)2y
So, the GCF is 2y and the expression factored is (x³y + 9xy − 10x² − 90)2y
Part B: Rewrite the expression completely factored.
2x³y² + 18xy² − 20x²y − 180y
Rearranging, we have
2x³y² − 20x²y + 18xy² − 180y
Separating them into brackets, we have
(2x³y² − 20x²y) + (18xy² − 180y)
Factorizing the expressions in bracket, we have
(xy − 10)2x²y + (xy − 10)18y
collecting like terms, we have
(xy − 10)(2x²y + 18y)
