A+n=7B

A-n=3B

2A=10B

Try to see if you can find the answer from there? If not, I will give you the solution. (I still think 17/7 is the correct answer though.)

it says its wrong

Let the amount of Alice's original money = A

Let the amount of Bob's original money = B

So

(A + n )* 7 =  (B - n)     →  7A - 2B  = -5n   (1)

(A - n) =  3 * ( B + n)  →  A - 3B  = 4n  (2)

Multiply the first equation by 3  and the second equation by 4  and add them together

3A -  9B  =  -12n

4A  - 8B =    12n

7A  - 17B  =  0     add 17B to both sides

7A  = 17B          divide both sides by 7, B

A / B  =  17/7

oh, thank you for spotting that!

If 20 people can pint 2000 square feet in 40 minutes we can find

how long it would take by just multiplying by 3, b/c 6000/2000=3

This results in 120 minutes, or 2 hours to paint a 6000 square foot yard.

I think my answer is correct

volume of 1st = π(36)(12) = 432π

volume of 2nd = π(64)h

64π h = 432π
h = 432π/(64π)
= 27/4

8 pi square units

The answer is 11:4.

read the question carefully they are different.
