One Step Inequalities

Front

What is an inequality?

Back

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

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'.

Front

What does the symbol '≥' mean?

Back

The symbol '≥' means 'greater than or equal to'.

Front

How do you solve the inequality p + 5 ≤ 18?

Back

Subtract 5 from both sides: p ≤ 13.

Front

What is the solution to the inequality k / -2 < 10?

Back

Multiply both sides by -2 (remember to flip the inequality): k > -20.

Front

How do you graph the solution of an inequality?

Back

Use a number line; use an open circle for < or > and a closed circle for ≤ or ≥.

Front

What does it mean to solve an inequality?

Back

To find all values of the variable that make the inequality true.

Front

What is the solution to the inequality -11x > 99?

Back

Divide both sides by -11 (flip the inequality): x < -9.

Front

How do you represent a situation with an inequality?

Back

Identify the quantities involved and express the relationship using inequality symbols.

Front

Back

15h ≥ 105, where h is the number of hours he works.
