Chapter 1 and 2 REVIEW
1) Simplify: 5y – (2y – 8)
2) Is 4 a solution of 6d – 7 > 17?
Explain your answer using 2 complete
sentences!
3) Evaluate the expression:
Answers
ANSWERS
1) 3y + 8
2) 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.
3) 34
19 – 4x + x3 when x = 3.
4) Write a variable expression for
6 times the sum of k and 3.
4) 6(k + 3)
5) Name all the number sets to
which the numbers belong.
(whole number, an integer, or a
rational number.)
5)
8 1/6
0
-99
8 1/6  Rational
0  Rational, Integer, Whole #
-99  Rational, Integer
7.28475…  Irrational
7.28475
6) Write a variable expression for
“16 less than a number, m,
cubed.
6) m3 - 16
7) Simplify:
7) 10r + 10
7(r + 1) + 3(r + 1)
8) Find the Product:
8) 54
(9)(-2)(3)(-1)
9) What is the multiplicative
inverse of -19?
9) -1/19
10)Simplify the expression:
20h – 4
4
10) 5h – 1
11)Find the quotient:
11) -20
8 ÷ (- 2/5)
12)Find the quotient:
12) First, change - 4 2/7 to an
improper fraction: - 30 / 7
8 ÷ (- 4 2/7)
Then: keep. Change. Flip.
(Multiply by the reciprocal)
Answer: -28/15
13)Tell whether the number is
rational or irrational. Give a
reason for your answer.
√7
√25
13)
√7  Irrational. 7 is not a perfect
square so the decimal will continue
forever.
√25  5. Rational. 25 is a perfect
square.
14) Identify the terms, like terms,
coefficients, and constant terms.
THEN, simplify the expression.
8c – 8 + 5 – 9c + 2c2
14)
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
15) Simplify:
15) - 5/4
- 3/8 ÷ 3/10
16)Simplify:
16) -50
(5)(-5)(2)
17)Estimate

18)Simplify:
29
17) The √29 is between
√25 and √36
Since 25 is closer to 29,
The √29 is ≈ 5.
18) -8p + 24
-8(p – 3)
19)Simplify:
5x7 + 14x7
19) 19x7
