1 Chapter 1 and 2 REVIEW

2 Simplify: 5y – (2y – 8)

3 3y + 8

4 Is 4 a solution of 6d – 7 > 17? Explain your answer using 2 complete sentences!

5 No, 4 is not a solution. When I substituted 4 in for d, the expression simplified into 17 > 17, which is not true. 17 is equal to 17, not greater than.

6 Evaluate the expression: 19 – 4x + x3 when x = 3.

7 34

8 Write a variable expression for 6 times the sum of k and 3.

9 6(k + 3)

10 Name all the number sets to which the numbers belong
Name all the number sets to which the numbers belong. (whole number, an integer, or a rational number.) 8 1/6 -99

11 8 1/6  Rational 0  Rational, Integer, Whole # -99  Rational, Integer …  Irrational

12 Write a variable expression for “16 less than a number, m, cubed.

13 m3 - 16

14 Find the change in temperature from 10*F to -16*F.

15 26*F

16 Simplify: 7(r + 1) + 3(r + 1)

17 10r + 10

18 Find the Product: (9)(-2)(3)(-1)

19 54

20 What is the multiplicative inverse of -19?

21 - 1/19

22 Simplify the expression:
4

23 5h - 1

24 Find the quotient: 8 ÷ (- 2/5)

25 -20

26 Find the quotient: 8 ÷ (- 4 2/7)

27 - 28/15

28 Tell whether the number is rational or irrational
Tell whether the number is rational or irrational. Give a reason for your answer. √7 √25

29 √7  Irrational. 7 is not a perfect square so the decimal will continue forever.
√25  5. Rational. 25 is a perfect square.

30 Identify the terms, like terms, coefficients, and constant terms
Identify the terms, like terms, coefficients, and constant terms. THEN, simplify the expression. 8c – – 9c + 2c2

31 Simplified Answer: 2c2 -1c – 3
8c – – 9c + 2c2 Terms: 8c, -8, 5, -9c, 2c2 Like terms: 8c, -9c AND -8, 5 Coefficients: 8, 2, and -9 Constant terms: -8 and 5 Simplified Answer: 2c2 -1c – 3

32 Simplify: - 3/8 ÷ 3/10

33 - 5/4

34 Simplify: (5)(-5)(2)

35 -50

36 Estimate

37 Since 25 is closer to 29, The is ≈ 5.
Is between and Since 25 is closer to 29, The is ≈ 5.

38 Simplify: -8(p – 3)

39 -8p + 24

40 Simplify: 5x7 + 14x7

41 19x7
