SOLUTION: I tried this problem by myself but not sure if I got it right, and have the feeling that I dont; If x varies as y and x=2 when y=8, find x when y=17; so y=k/x 8=k/2 k=16 y

Question 199485: I tried this problem by myself but not sure if I got it right, and have the feeling that I dont;
If x varies as y and x=2 when y=8, find x when y=17;
so y=k/x 8=k/2 k=16 y=16/x y=17 so 17=16/x x=16/17
I know I am a mess when it comes to algebra.....

Slight mis-step there. You wrote: . That means varies inversely as . If varies as (meaning directly as), then you want:



So if when , then



So:







On the other hand, if you simply left out the word 'inversely' when you posted the problem (and I think that may be the case because I have seen this particular problem before) then you did it correctly.
