Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or equal to the other.

What does the symbol '<' mean in inequalities?

Back

The symbol '<' means 'less than'. For example, 'c < 36' means c is less than 36.

Front

What does the symbol '>' mean in inequalities?

Back

The symbol '>' means 'greater than'. For example, 'p > 18' means p is greater than 18.

Front

What does the symbol '≤' mean in inequalities?

Back

The symbol '≤' means 'less than or equal to'. For example, 'x ≤ 10' means x is less than or equal to 10.

Front

What does the symbol '≥' mean in inequalities?

Back

The symbol '≥' means 'greater than or equal to'. For example, 'y ≥ 5' means y is greater than or equal to 5.

How do you solve the inequality x - 4 ≤ 6?

Back

Add 4 to both sides: x ≤ 10.

Front

How do you solve the inequality w + 4 ≤ -5?

Back

Subtract 4 from both sides: w ≤ -9.

Front

How do you solve the inequality y + 7 ≥ 12?

Back

Subtract 7 from both sides: y ≥ 5.

Front

What is the solution set for the inequality c < 36?

Back

The solution set includes all values of c that are less than 36.

Front

What is the solution set for the inequality p ≥ 18?

Back

The solution set includes all values of p that are 18 or greater.
