One-Step Inequalities (Addition and Subtraction)

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?

Back

The symbol '<' means 'less than'. For example, 3 < 5 means 3 is less than 5.

Front

What does the symbol '>' mean?

Back

The symbol '>' means 'greater than'. For example, 7 > 2 means 7 is greater than 2.

Front

How do you represent 'a number decreased by 5 is less than 12' as an inequality?

Back

n - 5 < 12.

Front

How do you represent 'a number increased by 3 is greater than 7' as an inequality?

Back

n + 3 > 7.

Front

What is the solution to the inequality x + 2 < 5?

Back

x < 3.

Front

What is the solution to the inequality x - 4 > 1?

Back

x > 5.

Front

How do you graph the inequality x < 2?

Back

Open dot on 2; shaded to the left.

Front

How do you graph the inequality x > -3?

Back

Open dot on -3; shaded to the right.

Front

What does it mean if an inequality has a closed dot on the number?

Back

A closed dot indicates that the number is included in the solution (≤ or ≥).
