Activity 2. Find the equation then solve for the missing value.

1. p varies directly as q and t, and p = 60 when q 24 and t = 5. Find p when q = 12 and t = 4.

2. v varies directly as w and u, and v = 28 when w = 8 and u = 7. Find v when w = 14 and u = 9.

3. Suppose y varies jointly as the square of x and z, and y = 21 when x = 3 and z = 7. Find y when x 6 and z = 2/3

4. Suppose y varies jointly as x and the square of z, and y = 4 when x = 50 and z = 2/5 Find y when x = ¼ and z = 4.

5. y varies directly as x and inversely as z, and
y = 6 when x = 8 and z = 4. Find y when x= 12 and z = 9.

6. a varies directly as b and c, and a = 90 when
b = 6 and c = 3. Find a when b = 4 and c = ½

7. a varies directly as b and inversely as c, and
a = 5 when b = 2 and c = 4. Find a when b = 5 and c = 25.

8. m varies directly as n and inversely as p, and m = 8 when n = ½ and p = ¼ Find m when n = ¾ and p = 3.

9. p varies directly as q and inversely as r, and
p = 6 when q = 12 and r = 0.5. Find p when q = 8 and r = ⅓.

10. m varies directly as n and inversely as p and m = 5 when n = ¾ and p = 1/5. Find m when n = 9
and p = 6.​
