Algebra I Review, part 2

Homework:

Solve. This will be collected Monday (8/24).

1. 4z= 132

2. -6 = c + 4

3. x/2 = -40

4. 4.6 + z = 3.6

5. w - 5 = -13

6. -m = 5

7. c/7 + 2 = 1

8. 5(z + 3) = 12

9. 6 - 3a/2 = -6

10. 4x + 2(x - 3) = 0

11. (3 + m)/2 = 5

12. 4(t - 7) + 6 = 30

13. 12 ∙ b ∙ 13 = 338

14. 4(5n + 7) - 3n = 3(4n - 9)

15. 12 - 23c = 7(9-c)

16. 4.7(2f - 0.5) = -6(1.6f - 8.3f)

Notes:

Variable ∙ Variable = Variable2

z ∙ z = z2

Distributive Property: Multiply the number, variable or sign (+ or -) on the outside of the parenthesis to every number on the inside of the parenthesis.

Example:

z(7-2z)
7z-2z2
