What is the first step in solving a one-step inequality?

• Add the same number to both sides

• Multiply both sides by zero

• Subtract the same number from both sides

• Use inverse operations to isolate the variable

What must you do when you multiply or divide both sides of an inequality by a negative number?

• Add a positive number to both sides

• Subtract a positive number from both sides

• Reverse the inequality sign

• Keep the inequality sign the same

What is the key concept to remember when dealing with inequalities and negative numbers?

• Reverse the inequality sign when multiplying or dividing by a negative

• Ignore the negative sign

• Always add a positive number

• Multiply by zero to simplify

If you have the inequality -5t < -40, what is the correct solution for t?

• t ≤ 8

• t = 8

• t < 8

• t > 8

Which of the following is NOT a step in translating word problems into inequalities?

• Ignore the units of measurement

• Circle the provided information

• Underline the question

• Read the problem carefully

When solving the inequality x + 5 < -12, what is the value of x?

• x < -17

• x > -17

• x ≤ -17

• x = -17

In the inequality y/3 ≥ 5, what operation should be performed to solve for y?

• Subtract 3 from both sides

• Add 3 to both sides

• Multiply both sides by 3

• Divide both sides by 3
