Basically, you just perform whatever operations are needed to get the variable you DON'T know by itself on one side of the equal sign, plug in the variables you do know, and you have it. In your example, say you don't know the length, but you know the others:
V = l*w*h
V/w*h = l*w*h/w*h
V/wh = l
Now l is by itself, so you can substitute values for the other variables and solve for l.

Josiah downloads 44 songs including 16 songs by his favorite band. Express as a decimal the number of songs by his favorite band

marin [14]

Using a calculator, 16/44 = 0.363636363636363636... it goes on and on. It is repeating. If it was terminating, you would see the end.

There are a few ways to report the number, I'm not sure which one you need. A common way to show a repeating decimal is to put a line above it, I will upload a picture of what I mean.

Otherwise, you can round it.

What is the answer to this problem?<br><br> X+ 5/12=5/8

Irina-Kira [14]

We we are asked to solve this kind of problem we are asked to find the value of the value (x in this case). So the first thing we want to do isolate x by subtracting 5/12 from both sides.

x+5/12-5/12=5/8-5/12

Simplify

x=5/8-5/12

Reduce

x=3/3(5/8)-2/2(5/12)

x=15/24-10/24

x=5/24
