Equations and Inequalities-6th Grade

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 x + 5 < 10?

Back

Subtract 5 from both sides: x < 5.

Front

What is the solution to the inequality 2x > 6?

Back

Divide both sides by 2: x > 3.

Front

What happens to the inequality sign when you multiply or divide by a negative number?

Back

The inequality sign flips (changes direction).

Front

If x - 4 ≥ 2, what is the value of x?

Back

Add 4 to both sides: x ≥ 6.

Front

What is the solution to the equation x + 13 = 63?

Back

Subtract 13 from both sides: x = 50.

Front

How do you graph the inequality x < 4?

Back

Draw a number line, place an open circle at 4, and shade to the left.

Front

What does the inequality -4x ≥ 10 require when solving?

Back

You must flip the inequality sign when dividing by -4: x ≤ -2.5.
