Answer:

1. z varies jointly as x and y and z = 60 when x = 5 and y = 6.

a. Find z when x = 7 and y = 6

b. Find x when z= 72 and y = 4

c. Find y when z= 80 and x = 4

2. If r varies directly as s and inversely as the square of u, and r = 2 when s = 18 and u = 3, find ;

a. r when u = 3 and s= 27

b. s when u = 2 and r = 4

c. u when r = 1 and s = 36
