studyhard Wrote:Aggh, I'm so fuzzy on this. This is a problem from the CLEP practice test. I'm putting parenthesis around things that are exponents, since there's no way to denote them:


If 8(x) = 15 and 8(y) = 25, then 8(2x +y) = ??????

I can't for the life of me remember how to work this problem and digging through my old math books shed no light. Any ideas?

I think (x =15 and (y)=25, therefore 8 x (2 x 15+ 25)
(30 +25) = 55
8 x 55 = 440
