which equation is NOT equivalent to the formula r = st??? s = r/t t = r/s s = t/r r = ts

OpenStudy (gabylovesyou):

is it C?

OpenStudy (anonymous):

yup u got it :)

By multiplying by a convenient variable on both sides you see that the third one is the one thats not equivalent. Because multipying it by t we get: st=t^2/r wich is deferent than the given formula.

cuz s=r/t not t/r :)
