Equation/Inequalities Review

Solve the inequality...

12x - 7 ≥ 53

• x ≥ 4

• x ≤ 4

• x ≤ 5

• x ≥ 5

Solve and graph the inequality.
7n - 1 > 76

• A

• B

• C

• D

3n + 4 = 7 

• 1

• -1

• 3.67

• 2

4c - 6 = 2 

• 2

• -2

• 1

• 3

Translate the statement into an equation:

Five less than a number is 6

• n - 5 = 6

• 5 - n = 6

• 6 - 5 = 1

Two more than 4 times a number is -18.

• 4x + 2 = -18

• 2x + 4 = -18

• 18 = 4x + 2

Translate the sentence into an inequality.

Four times a number increased by  7 is at least 19. 

• 4x > 19

• 4x + 7 ≥ 19

• 4x < 19

• 4x + 7 ≤ 19

x + 5 ≤ 13

• x ≥ 8

• x ≥ 18

• x ≤ 8

• x ≤ 18

x - 4 > 5

• x < 9

• x ≥ 9 

• x > 1

• x > 9

Does the sign need to flip when solving?
-2x ≥ 22

• YES

• NO
