y x, and y = 45 when
z = 6

Solve for y when x = 6,z = 10

Joint variation equation:

Varies jointly means y = kxz where k is a constant

Plug in y = 45 when z = 6 and x = 1/2

45 = (6)(1/2)k

45 = 6k

Divide each side by 6

k = 7.5

Solve the second part of the variation

With k = 7.5, we form our new variation equation:

y = 7.5xz

Given that x = 6,z = 10

Since we were given that x = 6,z = 10, we have

y = 7.5 * 6 * 10

y = 450
