Solving one step inequalities using 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 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

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

Back

The symbol '≥' means 'greater than or equal to'. For example, x ≥ 4 means x 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, x ≤ 2 means x is less than or equal to 2.

Front

How do you solve the inequality x + 3 > 10?

Back

Subtract 3 from both sides: x > 7.

Front

How do you solve the inequality x - 5 < 12?

Back

Add 5 to both sides: x < 17.

Front

What is the solution to the inequality 2x ≥ 10?

Back

Divide both sides by 2: x ≥ 5.

Front

If r - 14 ≥ 17, what is the value of r?

Back

Add 14 to both sides: r ≥ 31.

Front

What inequality represents 'a number is at least 3'?

Back

x ≥ 3.
