How do you solve the inequality s + 9 ≥ -25?

Back

Subtract 9 from both sides to get s ≥ -34.

Front

What is the first step in solving the inequality 2x + 7 > 15?

Back

Subtract 7 from both sides to get 2x > 8.

Front

What happens to the inequality sign when you multiply or divide by a negative number?

Back

You must flip the inequality sign.

r = 165.

Front

What is a one-step inequality?

Back

A one-step inequality is an inequality that can be solved in a single operation, such as addition, subtraction, multiplication, or division.

Front

What is a two-step inequality?

Back

A two-step inequality requires two operations to solve, such as adding or subtracting first, then multiplying or dividing.
