Solve and Model Equations and Inequalities

• A
• B
• C
• D

The model represents an equation.

What value of x makes the equation true?

• 3

• 8

• 6

• 4

What is the solution to this inequality?

• x > −18

• x > 9

• x > 21

• x > −42

Solve the following inequality and choose the best answer: 4x - 8 < -16

• The graph would be an open circle shading right of 2

• The graph would have a closed circle shading left of -2

• The graph would have an open circled shading left of -2

• The graph would have a closed circle shading right of 2

What is the value of x in this equation?

2x + 2 = −52

• −25

• −27

Solve: x + 12 = 19

• x = 21

• x = 31

• x = 7

• x = 5

When solving an inequality, you must flip the sign when?

• Adding or subtracting a negative number

• Multiplying or dividing by a negative number

• Never

• Always

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5

• Add 6 to both sides and multiply both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Subtract 6 from both sides then divide both sides by 5

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3
