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 in inequalities?

Back

The symbol '>' means 'greater than'. For example, x > 10 means x is greater than 10.

Front

What does the symbol '<' mean in inequalities?

Back

The symbol '<' means 'less than'. For example, x < 5 means x is less than 5.

Front

What does the symbol '≤' mean in inequalities?

Back

The symbol '≤' means 'less than or equal to'. For example, x ≤ 4 means x is less than or equal to 4.

Front

What does the symbol '≥' mean in inequalities?

Back

The symbol '≥' means 'greater than or equal to'. For example, x ≥ 3 means x is greater than or equal to 3.

Front

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

Back

Add 24 to both sides: k ≤ 34.

Front

How do you solve the inequality 15 > -5 + z?

Back

Add 5 to both sides: z < 20.

Front

How do you solve the inequality 23 < f + 12?

Back

Subtract 12 from both sides: f > 11.

Front

What does the solution k ≤ 34 represent on a number line?

Back

It represents all numbers less than or equal to 34, including 34.

Front

What does the solution z < 20 represent on a number line?

Back

It represents all numbers less than 20, not including 20.
