What is the value of fraction 1 over 2 x4 + 5.2y, when x = 2 and y = 3

4 answers

what's the problem? Just plug in the numbers:

(2x^4)/(5*2y) = (2*2^4)/(5*2*3) = 32/30 = 16/15

Hard to say, though, given your probable typos. If I got it wrong, fix my mistake and then plug in the numbers as I did.
the answers on my test say 23.6, 24.6, 27.6 or 39.6 so idk what to put as my answer.
On my test its decimles not fractions. idk what to put.......
I know that it says that on your test but I got this answer, 19.6
