Answer 2

yes, but im not sure exactly how to

Answer 3

Okay, so it says that y = 32. So for why in you equation put 32 in for where y is. :)

Answer 4

32 = (x/32) * 125. (It is times 125, right?

Answer 5

ok, that makes sense

Answer 10

So now, you need to get the 32 out of the fraction bar. do you know how to do that?

Answer 11

wouldnt i have to multiply both sides by 32?

Answer 12

we need to get the 32 out so x will be by itself.

Answer 13

correct!

Answer 14

so what is 32 * 32?

Answer 15

(you can use a calculator)

Answer 16

1024

Answer 17

okay, so now we have 1,024 = x * 125 (or 125x, so it is actually 1,024 = 125x.) We will change this to make it easier. It is now 125x = 1024. what now?

Answer 18

well, its .125 (1/8)

Answer 19

I don't know exactly what you did, but you divide the 125. So you have x = 1024/125. Us a calculator.
