If X varies jointly as Y and Z, find the constant of variation if X = 5, Z = 8, Y = 480.
If x is proportional to yz then x = kyz for some constant, k You are given values of x, y, and z. Plug them in and you will obtain the value of k.
\[x \alpha yz\] \[x=kyz\] \[k=x/yz\] Here X = 5, Z = 8, Y = 480. Put the values and find K
