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, y < 3 means y is less than 3.

Front

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

Back

The symbol '≥' means 'greater than or equal to'. For example, z ≥ 4 means z is greater than or equal to 4.

Front

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

Back

The symbol '≤' means 'less than or equal to'. For example, a ≤ 7 means a is less than or equal to 7.

Front

How do you solve the inequality n - 30 > -32?

Back

Add 30 to both sides: n > -2.

Front

How do you solve the inequality 126 < f + 32?

Back

Subtract 32 from both sides: f > 94.

Front

What inequality is represented by the graph where the open circle is at 2.75 and the line extends to the right?

Back

2.75 < d.

Front

How do you solve the inequality -4 + y < -8?

Back

Add 4 to both sides: y < -4.

Front

What inequality is represented by the graph where the closed circle is at 11 and the line extends to the left?

Back

11 ≤ a.
