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.
