One Step Inequalities

Front

What is an inequality?

Back

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

Front

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

Back

The symbol '>' means 'greater than'. For example, x > 5 means x is greater than 5.

Front

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

Back

The symbol '<' means 'less than'. For example, x < 3 means x is less than 3.

Front

How do you solve the inequality x + 9 > 21?

Back

Subtract 9 from both sides: x > 12.

Front

What is the solution to the inequality 8x < 48?

Back

Divide both sides by 8: x < 6.

Front

How do you solve the inequality -8x < 48?

Back

Divide both sides by -8 (remember to flip the inequality): x > -6.

Front

What does the inequality 2.75 < d mean?

Back

It means that d is greater than 2.75.

Front

How do you solve the inequality m - 9 ≤ 20?

Back

Add 9 to both sides: m ≤ 29.

Front

What is the difference between '≤' and '<'?

Back

'≤' means 'less than or equal to', while '<' means 'less than' only.

Front

What does it mean if an inequality has no solution?

Back

It means there are no values that can satisfy the inequality, such as x < x.
