Question

If X varies jointly as Y and Z, find the constant of variation if X = 5, Z = 8, Y = 480.

Answer 1

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.

Answer 2

\[x \alpha yz\]

\[x=kyz\]

\[k=x/yz\]

Here

X = 5, Z = 8, Y = 480.

Put the values and find K
