Write an equation that expresses the following relationship. d varies directly with the cube of w and inversely with p. in your equation, use k as the constant of proportionality.

Here d varies directly with cube of w, and inversely with p. So w cube have to be in the numerator and p have to be in the denominator. And we need to use k for constant of proportionality. Therefore the required equation is

In direct proportionality, the relatioship is linear that is as w increases, d increases and as w decreases d decreases and for inverse, it is opposite .

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
