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

'≤' means 'less than or equal to'. It indicates that one value is either less than or equal to another.

Front

How do you solve the inequality m - 9 ≤ 20?

Back

Add 9 to both sides to isolate m: m ≤ 29.

Front

What does the solution to an inequality represent?

Back

The solution represents a range of values that satisfy the inequality.

Front

How do you graph the inequality 2.75 < d?

Back

Draw a number line, place an open circle at 2.75, and shade to the right to indicate all values greater than 2.75.

Front

What is the first step to solve (n/3) > -20?

Back

Multiply both sides by 3 to eliminate the fraction: n > -60.

Front

What does the symbol '>' mean?

Back

'>' means 'greater than'. It indicates that one value is larger than another.

Front

How do you represent the solution set of x - 3 > -3 on a number line?

Back

Draw an open circle at 0 and shade to the right to indicate all values greater than 0.

Front

What is the difference between '>' and '≥'?

Back

'>' means greater than, while '≥' means greater than or equal to.

Front

How do you solve the inequality 5x < 20?

Back

Divide both sides by 5: x < 4.
