Part I: Patterns & Graphing

Name:

Find the next three terms in each sequence.

1.

18, 32, 46, 60, 74, …

2.

100, 94, 88, 82, 76, …

3.

14, 21, 28, 35, 42, …

4.

1, 2.5, 4, 5.5, 7, …

5.

1, 4, 9, 16, 25, …

6.

2, 5, 10, 17, 26, …

Graph each point and label it with the appropriate letter. On the line next to the point write the quadrant or axis where the point lies. (I, II, III, IV, x-axis, y-axis)

Part 2: Operations with Real Numbers

Use the Order of Operations to evaluate each expression.

1.

(7 + 3

2

) – 2 ∙ 4

2.

187 – 34 ÷ 17

3.

4

2

∙ 2 + [7 – (3

2

– 5)]

4.

3(2 + 7 – 8) + 16

5.

4[(3 + 2 ∙ 3) – 5] + 7

Perform the indicated operation.

6.

-39 + 68

7.

-23 + (-25)

8.

9 – (-15)

9.

-23 – (-72)

10. (-12)(-5)

11. 54 ÷ (-18)

12. 45 [8 + (-8)]

13. (-3)(4 – 7)

ADDING AND SUBTRACTING WITH

LIKE DENOMINATORS

(1) Add numerators

(2) Keep denominator

MULTIPLYING FRACTIONS

(1) Multiply across top and across bottom

(2) Reduce

Perform the indicated operation.

14. 18.

15. 19.

16. 20.

17. 21.

Combine Like Terms

Add like terms with the same variable & exponent

(2x + 3) + (5x – 6) = (2x + 5x) + (3 – 6) = 7x – 3

(4d – 2) – (5d – 3) = (4d – 5d) + [-2 –(-3)]

= -1d + ( -2 + 3)

= -d + 1

Distribute

Multiply outside term by every part inside ( )

2(3x – 6) = 2∙ 3x – 2 ∙ 6 = 6x – 12

2

3x (2x – 4) = 3x ∙ 2x – 3x ∙ 4 = 6x – 12x

Simplify the expressions.

22. (3x + 4) + (2x – 1)

23. (4a + 3b) – (2a + 5b)

24. (-4x + 3) – (-6x + 3)

25. (2q + 3) – (-4q + 5) + (6q – 7)

26. 8(5x -9)

27. 3x(-5x – 4)

28. (5x – 7) – 3(2x – 1)

29.

30.

Part 3: Solving Equations

CHECK:

Solve.

1.

5x + 9 = 39

2.

6 – 2d = 42

3.

15 = – 2

4.

9p + 20 = -7

5.

5.2 + 1.3x = -1.3

6.

– 5 = -17

Solve.

7.

4n – 2 + 7n = 20

8.

5s + 7 – 2s = 16

9.

4(f + 2) = 20

10.

-4x + 4 – 2x = -5

11. 2x – 2 = 4x + 6

12. 3x + 5 = 2x + 2

13. 5m – 7 = -6m – 29

14. 2(x + 1) = 3x – 3
