What is an inequality?

Back

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

What does the symbol '>' mean in inequalities?

Back

The symbol '>' means 'greater than'. For example, x > 3 means x is greater than 3.

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 'greater than or equal to'. For example, x ≥ 2 means x is either greater than 2 or equal to 2.

Front

What does the symbol '≤' mean in inequalities?

Back

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

How do you solve the equation k ÷ 8 = 4?

Back

To solve for k, multiply both sides by 8: k = 4 * 8 = 32.

Front

What is the solution to the equation x + 17 = 21?

Back

To solve for x, subtract 17 from both sides: x = 21 - 17 = 4.

Front

What is the solution to the equation x - 8 = 4?

Back

To solve for x, add 8 to both sides: x = 4 + 8 = 12.

Front

What is the solution to the equation -6x = 24?

Back

To solve for x, divide both sides by -6: x = 24 / -6 = -4.

What does a number line represent in inequalities?

Back

A number line visually represents the set of solutions to an inequality, showing which values satisfy the inequality.
