• x > 5

• x ≤ 5

Write x > 7 in words.

• x is greater than 7

When you graph an inequality on a number line, you use a closed circle to represent which symbols?

• ≤, ≥

• <, >

• ≤, <

• ≥, >

You have 30 minutes to finish 12 problems for homework. Write and solve an inequality that represents how many minutes you can spend per problem.

• 30 ≤ 12x,  x ≥ 2.5
• 30x  ≤ 12 , x ≤ .4
• 30x -12  ≤ 18  , x  ≤  1
• 12x ≤  30  , x  ≤  2.5

When do you "flip the inequalities sign"?

• When you add or subtract a negative

• When it's a 1-step problem

• When you multiply or divide a negative

• When it's a 2-step problem
