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?

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 30 + n ≥ 50?

Back

Subtract 30 from both sides: n ≥ 20.

Front

What is the solution to the inequality -8x < 48?

Back

Divide both sides by -8 (remember to flip the inequality): x > -6.

Front

How do you graph the solution of an inequality?

Back

Use a number line to represent the solution set, using an open circle for < or > and a closed circle for ≤ or ≥.

Front

What is the solution to the inequality 7n > 49?

Back

Divide both sides by 7: n > 7.

Front

What does it mean to 'flip' the inequality sign?

Back

You flip the inequality sign when you multiply or divide both sides of an inequality by a negative number.

Front

What is the solution to the inequality r - 14 ≥ 17?

Back

Add 14 to both sides: r ≥ 31.

Front

What is a one-step inequality?

Back

A one-step inequality is an inequality that can be solved in a single step, usually by adding, subtracting, multiplying, or dividing.
