702-703 Memorial Day Review

The owner of a city parking garage uses a rate table so that he can look up the parking charges quickly.

What is the unit rate?

• $4.50

• $6.75

• $5.25

• $7.50

Determine the constant of proportionality for the table. Express your answer as y = kx

• y = 1/2x

• x = 1/2y

• y = 2x

• k = x

2 - 4

• 2
• -8
• 6
• -2

-5 - (- 3)

• -8
• 8
• -2
• 15

What is the opposite of 10? 

• 10
• -10
• 0
• 20

-3a + 8 = 14

• a= -2
• a= -7.5
• a= 2
• a= 6

-5 - 6a = -59

• a= 11
• a= -6
• a= 9
• a= 2

Simplify the expression: 7v + 2 + 12 + 2v

• 23
• 23v
• 9 + 14v
• 9v + 14

Simplify by combining like terms:
5a + 2b - 3a + 4

• 8a + 2b + 4
• 2a + 2b + 4
• 8ab
• 4ab + 4

What are complementary angles?

• Angles that add up to 180°

• Angles that add up to 90°

• Angles that are equal to each other

• Angles that are opposite of each other when lines intersect.
