Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols like <, >, ≤, or ≥.

Front

What does the symbol '≥' mean?

Back

'≥' means 'greater than or equal to'.

Front

What does the symbol '≤' mean?

Back

'≤' means 'less than or equal to'.

Front

How do you solve the inequality n - 8 ≥ 3?

Back

Add 8 to both sides: n ≥ 11.

Front

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

Back

You must flip the inequality sign.

Front

Solve the inequality -9h > -63.

Back

Divide by -9 (flip the sign): h < 7.

Front

What is the solution to the inequality -48 < 12c?

Back

Divide by 12: c > -4.

Front

How do you solve the inequality -24 + k ≤ 10?

Back

Add 24 to both sides: k ≤ 34.

Front

What is the solution to the inequality 5x < 20?

Back

Divide by 5: x < 4.

Front

What does it mean if a solution is 'x > 3'?

Back

It means x can be any number greater than 3.
