Section 9.1 #16 (pg. 671)
Place each of the following sets in ascending order.
16. / Convert to a common denominator (14):
6/14, -12/14, 2/14, -7/14, 4/14
Now order them by numerator:
-12/14, -7/14, 2/14, 4/14, 6/14
And put them back in their original form:
-6/7, -1/2, 1/7, 2/7, 3/7
Section 9.1 #32 (pg. 672)
Evaluate.
32. |4| + |-3| / |4| + |-3|
= 4 + 3
= 7
Section 9.1 #44 (pg. 672)
Evaluate.
44. |-9| – |-4| / |-9| - |-4|
= 9 - 4
= 5
Section 9.2 #40 (pg. 683)
Add.
40. 7 + (-9) + (-5) + 6 / = 7 – 9 – 5 + 6
= -2 – 5 + 6
= -7 + 6
= -1
Section 9.2 #48 (pg. 683)
Add.
48. / = 1/3 – 5/6 – ½
= 2/6 – 5/6 – 3/6
= -3/6 – 3/6
= -6/6
= -1
Section 9.2 #58 (pg. 683)
Evaluate the following expression.
58. |-27 + 14| / Do the inside:
|-13|
Evaluate:
= 13
Section 9.2 #66 (pg. 684)
Label the following statement as true or false.
66. |-8| + |3| = |-8 + 3| / Check the value of each side:
left side: |-8| + |3| = 8 + 3 = 11
right side: |-8 + 3| = |-5| = 5
FALSE
Section 9.2 #72 (pg. 684)
72.Jean deposited a check for $625, wrote two for $68.74 and $29.95, and used her debit card to pay for a purchase of $57.65. How has her account balance changed? / + 625 - 68.74 - 29.95 - 57.65
= 556.26 - 29.95 - 57.65
= 526.31 – 57.65
= $468.66 increase
Section 9.3 #44 (pg. 689)
Subtract.
44. / -1/2 - (-5/8)
Common denom:
-4/8 + 5/8
= 1/8
Section 9.3 #48 (pg. 689)
Subtract.
48. -3.4 – (-7.6) / -3.4-(-7.6)
= -3.4 + 7.6
= 4.2
Section 9.3 #54 (pg. 689)
54. The lowest temperature ever recorded in the state of Oregon was –54°F (in Seneca, on February 10, 1933). The state’s record high temperature occurred in Pendleton on August 10, 1898, when it reached 119°F. What is the historical temperature range in the state of Oregon? / range = high - low
= 119 - (-54)
= 119 + 54
= 173 degrees
Section 9.4 #70 (pg. 700)
Multiply and add as indicated.
70. (-3)(-6) + (4)(-2) / = 18 – 8
= 10
Section 9.4 #80 (pg. 700)

Multiply and subtract as indicated.
82. (-6)2 – 42 / = 36 – 16
= 20
Section 9.4 #88 (pg. 701)
Multiply and subtract as indicated.
88. -92 – (-6)2 / = -81 – (36)
= -117

Perform the indicated operation.
32. / = -45/-3
= 45/3
= 15
Section 9.5 #58 (pg. 709)
Evaluate the following. Remember to use the order of operations.
58. / = -8*-4 / (8+4)
= 32/12
= 16/6
= 8/3
