• add 12 to both sides

• subtract 12 from both sides

Multiple Choice

What is the new inequality on number 1?

• 3m < -14.1

• 3m > -14.1

• 3m < -9.9

• 3m > -9.9

Multiple Choice

What is the next step to solve 3m < - 14.1

• add 3 to both sides

• subtract 3 from both sides

• multiply 3 on both sides

• divide 3 from both sides

Multiple Choice

Which answer choice matches your answer for -14.1 ÷ 3?

Multiple Choice

On question 2 on your paper, look at the inequality 3(4r + 2) > 30. What is the first step to getting the r by itself?

• subtract 2 from both sides

• divide 3 from both sides

• subtract 3 from both sides

• divide by 4 on both sides

Multiple Choice

After dividing 3 on both sides, what is the new inequality?

• 4r + 2 ≥ 10
• 4r+2 > 10

• 4r + 2 ≤ 10

Multiple Choice

For your new inequality, 4r + 2 > 10, what is the next step to solve?

• add 4 on both sides

• divide 4 on both sides

• add 2 on both sides

• subtract 2 on both sides

Multiple Choice

After subtracting 2 from both sides, what is the new inequality?

• 4r ≥ 8

• 4r ≥ 12

• 4r + 4 ≥ 8

• 4r ≥ 2.5

Multiple Choice

What is the next step to solve 4r ≥ 8?

• Add 4 on both sides

• Subtract 4 on both sides

• Multiply 4 on both sides

• Divide 4 on both sides

Multiple Choice

What is the inequality after you divide 4 on both sides?

• r ≥ 2

• r > 2

• r ≥ - 2

• r ≤ 2

Multiple Choice

Look at the inequality -4s + 6 ≥ -30 on question 2. What is the first step?

• Add 4 to both sides

• Subtract 4 on both sides

• Add 6 to both sides

• Subtract 6 on both sides

Multiple Choice

What is the new inequality after you subtract 6 on both sides?

• -4s ≤ -36

• -4s ≥ -36

• -4s ≤ -24

• -4s ≥ -24

Multiple Choice

What is the next step to solve -4s ≥ -36

• Add -4 to both sides

• Multiply -4 to both sides

• Subtract -4 on both sides

• Divide -4 on both sides

Multiple Choice

Does the sign flip or stay the same?

• Flip

• Stay the same

Multiple Choice
