• less than or equal to

• greater than or equal to

Translate the sentence into an inequality.
Seven less than n is greater than or equal to 18.

• n - 7 > 18

• 7 - n ≥ 18

• n - 7 ≥ 18

• n + 7 ≥ 18

Write an inequality for this situation:
You are driving, and the maximum speed limit is 55.

• s < 55

• s > 55

• s ≤ 55

• s ≥ 55

Match the graph with its inequality.

• a > 11

• a < 11

• a ≥ 11

• a ≤ 11

Find the error in the problem below

19 - 2k = 3k - 1

+3k +3k

19 + 1k = -1

-19 -19

k = -20

• They should have divided by 1 for the last step

• They should add 19 instead of subtracting 19

• I can not find an error

• Instead of adding 3k they should subtract 3k

What is the first step in solving the following problem?

2x+10=22

• Add 10 to each side

• Divide by 2

• Subtract 10 from each side

• Multiply by 10

The objective when solving an equation is to....

• isolate the variable.

• check the solution.

• guess and check.

• Combine Like Terms.
