Solve each inequality. Then, check your answer using a value that makes your solution true.

For each of the following statements:

• Use a number line to show which values satisfy the inequality.
• Express the statement symbolically with an inequality.

1. The elevator can lift up to 1,200 pounds. Let  represent the weight being lifted by the elevator.

   

2. Over the course of the senator's term, her approval rating was always around 53%, ranging 3% above or below that value. Let   represent the senator’s approval rating.

   

3. There's a minimum of 3 years of experience needed. Let  represent the years of experience for a candidate that meets this requirement.

   

Your teacher will give you a set of cards that show a graph, an inequality, or a situation.

1. Sort the cards into groups of your choosing. Be prepared to explain the meaning of your categories.
2. Then sort the cards into groups in a different way. Be prepared to explain the meaning of your new categories.
