Congruent (the same)

400

Angle ABC and Angle CBD are Supplementary. If the measure of Angle ABC is 115 degrees, what is the measure of Angle CBD?

65 degrees

500

Angle ABC and Angle CBD are Complementary. If the measure of Angle ABC is 48 degrees, what is the measure of Angle CBD?

42 degrees

Equivalent Expressions

100

Write an equivalent expression to 3(x - 6).

3x - 18

200

Simplify this expression: 4x - 3x + 4x - 2x

3x

300

Factor the following expression: 5x - 40

(Write it as a number times two terms in parentheses)

5(x - 8) or 5 times the sum of "x" minus eight.

400

Simplify: 2(3a+2b−7)

6a + 4b - 14

500

Simplify: 56x+40y-48z

8(7x+5y-6z)

Solving for X

100

Solve for x:  x - 5 = -4

x = 1

200

Solve for x:  3x - 2 = -5

x = -1

300

Solve for x:  (2/3)x = 10

x = 15

400

Solve for x:  -4x - 29 = -5

x = -6

500

Solve for x:  7x - 5 = 163

x = 24

Inequalities

100

On the graph of an inequality, a circle that is shaded tells us what?

≥ or ≤ (Greater than or equal to symbol or the less than or equal to symbol, and the endpoint is included in the solution.)

200

Solve -3x > 6 for x. (Remember, the coefficient is negative.)

x < -2

300

The graph of an inequality has a shaded circle above 4 with an arrow running to the left. What inequality would represent this situation?

"x" is less than or equal to 4, or x≤4

400

What happens if you multiply or divide both sides of an inequality by a negative number?

The inequality symbol reverses.

500

Solve this inequality for x:  5x - 2 ≤ -2

x ≤ 0

Miscellaneous

100

Given a pair of Complementary angles where one angle measures 37 degrees, what is the measure of the other angle?

53 degrees

200

If you divided both sides of an inequality by -4, what would happen?

The inequality symbol reverses, so that < becomes >, and > becomes <, and so on.

300

John has $55. He buys 6 books. Each book costs the same amount, b. He now has $10.

Write an equation that represents this situation.

55 = 6b + 10

400

A plumber charges a one-time fee of $75 plus a fixed hourly rate, h, in dollars.  The plumber works at a customer’s house for 2 hours and charges a total of $205.

Write an equation to represent this situation.

75 + 2h = 205

500

Solve for x:  4x + 7 = 14x +2

x = 1/2
