Solving Two-Step Inequalities

Solve the inequality: 2a + 3 ≥ 15, thus a is (a)  

• a = 0
• a > 15
• a ≤ 6
• a ≥ 6

Answer explanation

To solve the inequality 2a + 3 ≥ 15, we first subtract 3 from both sides to get 2a ≥ 12. Then, divide by 2 to find a ≥ 6. Therefore, the correct answer is a ≥ 6.

Solve the inequality.
-10x + 5 ≥ 195

• x ≤ -19
• x ≥ -19
• x < -19
• x > -19

-3 +6b < 21

• b < 4

• 12 > b

• b > 12

• b > 4

4x - 4 ≥ -20

• x ≥ -6

• x ≥ -4

• x ≤ -4

• x ≤ -6

6 - 2h > -18

• h < 12

• 14 > h

• h > 12

• h < -12
