3.2.2 Solving Inequalities with Variables on Both Sides - Practice

1.  Solve the inequality 4 x < 2 x + 16 and graph the solutions.

2.  Solve the inequality and graph the solutions. 7 x − 41 ≤ 6.2 x + 7

3.  Mrs. Williams is deciding between two field trips for her class. The Science Center charges \$110 plus \$7 per student. The Dino Discovery Museum simply charges \$9 per student. For how many students will the Science Center charge less than the Dino Discovery Museum?

4.  John bought a computer scanner and supplies for \$215.70, which will allow him to scan images for \$0.34 each. A computer center charges \$0.59 to scan each image. How many images must John scan before his total cost is less than getting scanned images at the computer center?

5.  Solve the inequality 2(3 x − 20) > − 4 x and graph the solutions.

6.  Solve the inequality − 5( x + 2) < − 5 x + 8.

7.  Solve the inequality − 2( k − 5) < −2 k + 2.

8.  Solve the inequality − 2(8 + 2 x ) < 4( − x − 4).

9.  Solve the inequality 7 y + 7(3 − y ) > 2 y − 9.
