Warm Up

Complete the two warm up questions at

the top of your page.

You will answer some questions about them

in the following questions.

Multiple Choice

What will have to be done to the inequality in this problem?

$$100-4x\ge20$$

• You will add 100 to both sides, so you will have to reverse the inequality symbol.

• You will multiply both sides by -4, so you will have to reverse the inequality symbol.

• You will divide both sides by -4, so you will have to reverse the inequality symbol.

• You will subtract 100 from both sides, so you will have to reverse the inequality symbol.

Multiple Choice

Solve.

$$100-4x\ge20$$

• $$x\le20$$

• $$x\ge20$$

• $$x\le-20$$

• $$x\ge-20$$

Math Response
