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.

Front

What does the symbol '>' mean in an inequality?

Back

The symbol '>' means 'greater than'. For example, in the inequality x > 5, x is any number greater than 5.

Front

What does the symbol '<' mean in an inequality?

Back

The symbol '<' means 'less than'. For example, in the inequality x < 3, x is any number less than 3.

Front

What does the symbol '≥' mean in an inequality?

Back

The symbol '≥' means 'greater than or equal to'. For example, in the inequality x ≥ 4, x can be 4 or any number greater than 4.

Front

What does the symbol '≤' mean in an inequality?

Back

The symbol '≤' means 'less than or equal to'. For example, in the inequality x ≤ 2, x can be 2 or any number less than 2.

Front

How do you solve the inequality 12x < 264?

Back

To solve 12x < 264, divide both sides by 12: x < 22.

Front

What is the first step to solve the inequality 12.25h + 25 ≥ 270?

Back

Subtract 25 from both sides: 12.25h ≥ 245.

Total savings after w weeks can be expressed as 18w.

Front

How do you represent the condition that Chloe needs to refill her bird feeder when there is less than 3 pounds of birdseed remaining?

Back

You can represent this condition with the inequality: 12.75 - 1.5d < 3.

Front

What is the solution to the inequality -18 > 6y?

Back

To solve -18 > 6y, divide both sides by 6: -3 > y or y < -3.
