Solve the indicated variable in each of the following. 1. If "y varies directly as x" and y = 24 when x = 4, find x when y = 18.
2. If "y varies inversely as x" and y = 18 when x = 4, find y when x = 3.
3. "z varies jointly as x and y". If z = 60 when x = 3 and y = 5, find y when z = 168 and x = 6.
4. If "y varies directly as x and inversely as the square of z", and y = 4 when x = 20 and z = 5, find y when x = 12 and z = 2.
