Draw 8 squares and then underneath it 12. Separate it so for every amount of this, there is an amount of this. Make sure they are even.

Use ratio ballet over hip hop

8/12= 1/X
Cross multiply
8x=12
Divide by 8
X= 3/2
So for each it's 1 1/2 one and one half

Use properties of equality to find the value of x in the equation 12(5x-4.5)=36

lukranit [14]

Answer:

x= 1.5 Hope that helps!

Step-by-step explanation:

1. 12(5x-4.5)=36 First Divide both by 12 5x-4.5-36/12 = 3

2. 5x-4.5=3 add 4.5 to both sides

3. 5x= 3+4.5 = 7.5

4. 5x=7.5 divide both sides by 5 x=7.5/5= x=1.5

So, x=1.5 would be your answer. Can you make me Brainliest Please

The height of a cylinder is 10 and the area of a base is 36 pi square units. What

ollegr [7]

Answer:

1130.97336 units^3

Step-by-step explanation:

The volume of a cylinder can be found using:

$v=\pi r^2h$

We have the area of the base, but not the radius

$a=\pi r^2$

We know the area is $36\pi$ , so we can substitute that in for a

$36\pi =\pi r^2$

We want to find r, so we need to isolate it

Divide both sides by pi

36=r^2

Take the square root of both sides

6=r

Now we know the radius, and can substitute it into the volume formula, and we can substitute the height (10) in

$v=\pi r^2h$

$v=\pi 6^210$

Solve the exponent

$v=\pi 36(10)$

$v=\pi 360$

v=1130.97336

The volume is 1130.97336 units^3

gogolik [260]

1. identify the abc... ax^2+bx+c
2. write down all the factor pairs of C
3. identify which factor pairs from the previous step sums up to letter B
