Equations and Inequalities!!!!

Choose the inequality for the number line.

• y < -1

• y < -1

• y > -1

• y > -1

Select the graph for the inequality x > 3

• A

• B

• C

• D

• add 5 to both sides

• multiply by 2/1

• subtract 5 from both sides

• divide by 2/1

 Which inequality could be used to represent the situation: A maximum of 5 students are chosen to be peer mediators. 

• x < 5
• x > 5
• x ≤  5
• x ≥ 5

• Yes

• No

-4x + 14 ≤ 54

• x ≥ -10
• x ≤ -10
• x ≥ 10

Write an inequality:

Jefferson had $500 in a saving account at the beginning of the summer. He takes out $25 each week to pay for Friday dinner out. He wants to keep more than $200 in the account, so what is the most number of weeks he could do Friday dinner out?

• 500 + 25x > 200

• 500 - 25x > 200

• 500 + 25x < 200

• 500 - 25x < 200
