Which of the following symbols is used to represent 'less than' in inequalities?

• ≥

• <

• >

What is the main difference between an inequality and an equation?

• Equations are always linear.

• Inequalities are harder to solve.

• Equations have a single solution, while inequalities can have infinite solutions.

• Inequalities use different symbols.

How do we represent that a number is not included in the solution set on a number line?

• Using a triangle.

• Using a closed circle.

• Using a square.

• Using an open circle.

What does an open circle on a number line indicate?

• The number is included in the solution set.

• The number is not included in the solution set.

• The number is less than the solution set.

• The number is greater than the solution set.

• To the right.

• To the left.

• Upwards.

• Downwards.

What does a closed circle on a number line indicate?

• The number is included in the solution set.

• The number is not included in the solution set.

• The number is greater than the solution set.

• The number is less than the solution set.
