marissalovescats · Answer

Joint variation is 

z=kxy.

marissalovescats · Answer

Or in your case, 

y=kpq

where K is a constant number.

marissalovescats · Answer

Soo 

30=k(1)(2)

marissalovescats · Answer

30=2k. 

What does K=? @johnrocks989

marissalovescats · Answer

Once we have found K, which we know is 15 because 30/2 is 15

We plug in p and q 

So y=(15)(10)(3)

So what does y=?
