Question

Can somebody help me and explain to me what this means?

"Practice representing two quantities using only one variable."

How do I do this?

Answer 1

a variable is like x, y or z. Quanity is how much is multiplied, etc by it.

Answer 2

No, I know this. I just don't know how to "represent two quantities using one variable".

Answer 3

Answer 4

example 2 quantities one is 7 more than the other
x, (x + 7)

Answer 5

example the length is twice the width
L = 2w so 2w, w

Answer 6

I agree with triciaal here. Supposing that one variable is represented by x, and that the second variable is 7 more than the first. Then the 2nd variable is x+7. Right.
