4th Test 2

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

10.    x / 2  - 5 = 3

• x = -2
• x = 2
• x = 16
• x = 8

x/5 - 13 = 20

• 145
• 165
• 180
• 190

When you graph an inequality, you used a closed dot when you use which symbols?

• ≤, ≥ 
• <, >

Solve the inequality.
x + 5 ≤ 13

• x ≥ 8
• x ≥ 18
• x ≤ 8 
• x ≤ 18 

Match the graph with its inequality.

• 11 < a
• 11 > a
•  11 ≤ a
•  11 ≥ a

10 ≥ x - 3

• x ≤ 13
• x ≥ 13
• x ≤ 7
• x ≥ 7

X - 10 > 25

• X > 35

• X < 35

• X > -35

• X < -35
