Question

best answer will be given

. If x varies inversely with y and x = 8 when y = 10, find y when x = 6.

Answer 1

i am having problems solving this.

Answer 2

I think I just figured this out its real confusing not even sure if i have it right.

Inverse variation formula y= k/x
substitue 8 for x and 10 for y 10 = k/8
multiply and solve for k 80=k
y=80/x
substitute 6 for x y=80/6
divide 80 by 6 y=80/13.333

here is a site it doesn't give you the answer but if you plug in the numbers it will tell you if your right or wrong.
