7th GRADE MILESTONE REVIEW - 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'. For example, 3 < 5 means 3 is less than 5.

Front

What does the symbol '>' mean?

Back

The symbol '>' means 'greater than'. For example, 7 > 4 means 7 is greater than 4.

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'. For example, x ≤ 10 means x can be any number less than or equal to 10.

Front

What does the symbol '≥' mean?

Back

The symbol '≥' means 'greater than or equal to'. For example, y ≥ 5 means y can be any number greater than or equal to 5.

Front

How do you solve the inequality -5m < 10?

Back

Divide both sides by -5 and reverse the inequality sign: m > -2.

Front

What is the solution to the inequality 10 ≥ x - 3?

Back

Add 3 to both sides: x ≤ 13.

Front

What inequality does the graph represent if it shows an open circle at 2 and shading to the left?

Back

The inequality is x < 2.

Front

What inequality does the graph represent if it shows a closed circle at 11 and shading to the right?

Back

The inequality is 11 ≤ a.

Front

How do you represent the inequality 2x - 3 < 7 on a number line?

Back

First, solve for x: 2x < 10, so x < 5. Shade to the left of 5 with an open circle.
