One and Two 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?

Back

The symbol '>' means 'greater than'. For example, 6 > 4 means 6 is greater than 4.

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 or equal to'. For example, x ≥ 5 means x is greater than or equal to 5.

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'. For example, y ≤ 10 means y is less than or equal to 10.

Front

How do you solve the inequality -2x ≤ 14?

Back

Divide both sides by -2 and reverse the inequality sign: x ≥ -7.

Front

What happens to the inequality sign when you multiply or divide by a negative number?

Back

The inequality sign flips. For example, if you have -x > 3 and divide by -1, it becomes x < -3.

Front

Solve the inequality: 6 > x. What does this mean?

Back

This means x is less than 6.

Front

Solve the inequality: 16 - 4a > 8. What is the solution?

Back

The solution is a < 2.

Front

What is the solution to the equation r/5 - 15 = 18?

Back

The solution is r = 165.
