Do You Know HOW?

Write an inequality that represents each verbal expression or graph.

1. all real numbers n that are less than –3

2. The product of 4 and z is greater than or equal to 7.

3. 4.

Solve each inequality. Graph the solutions.

5. 6m + 1 ≤ 3m – 8 6. 4(3w – 1) ≥ 20

7. 3

b> 8. –2.2t ≥ 11

Solve each inequality, if possible. If the inequality has no solution, write

no solution. If the solutions are all real numbers, write all real numbers.

9. 8n – 20 < 4(2n – 5) 10. 4d – 9 ≤ 6d + 15

11. 5t – 6 – 3t ≤ 2(t – 2) 12. 8 – 7x > 15
