Back

The symbol '≤' means 'less than or equal to'.

Front

How do you solve the inequality X/5 ≥ 7?

Back

Multiply both sides by 5: X ≥ 35.

Front

What is the solution to the inequality 24 ≤ h + 15?

Back

Subtract 15 from both sides: h ≥ 9.

Front

How do you solve the inequality -8x < 48?

Back

Divide both sides by -8 (remember to flip the inequality): x > -6.

Front

What is the solution to the inequality -3 ≥ x - 1?

Back

Add 1 to both sides: -2 ≥ x or x ≤ -2.

Front

How do you solve the inequality k/-12 ≤ -7?

Back

Multiply both sides by -12 (flip the inequality): k ≥ 84.

Front

What is the first step in solving one-step inequalities?

Back

Identify the operation being performed on the variable and perform the inverse operation.

Front

What does it mean to 'flip' the inequality sign?

Back

You flip the inequality sign when you multiply or divide both sides of an inequality by a negative number.
