Simplify by combining like terms

1. 5 + 10s – 8s
2. -5a – 4a + b
3. 2a + 3b + 4a
4. 6r + 3s + 2s
5. 7b – (3a – 8b)

Solve each formula for the indicated variable

6. A = 1/2h(b, +b2) Solve for b2

7. S = 2piR^2 + 2piRh Solve for h

8. h = vt – 5t^2 Solve for V

Solve each inequality, then graph the solution

9. 3 _> -12 and 8x _< 16

10. 4x < 16 or 12x > 144

11. -6 < 2x – 4 < 12
