Solve:

-8b - 8 > 56

• b > 6

• b < -8

• b > -8

• b > 7/2

Match the graph with its inequality.

• a > 11

• a < 11

• a ≥ 11

• a ≤ 11

Pick the correct letter for the graph of:

6 > x

Hint: You need to REWRITE the inequality with the variable first.

Sue's lunch account has $25 and she spends $2.50 every day. Troy's lunch account has $50 and she spends $3.25 every day. Write an inequality that shows when Sue's account will be more than Troy's.

• 25 - 2.5d > 50 - 3.25d

• 25 - 2.5d < 50 - 3.25d

• 25 + 2.5d > 50 + 3.25d

• 25 + 2.5d < 50 + 3.25d
