One and two 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 'greater than or equal to'.

Front

What does the symbol '≤' mean?

Back

'≤' means 'less than or equal to'.

Front

How do you solve the inequality: s + 9 ≥ -25?

Back

Subtract 9 from both sides: s ≥ -34.

Front

What is the solution to the inequality: -2x ≤ 14?

Back

Divide both sides by -2 (remember to flip the inequality): x ≥ -7.

Front

How do you represent a maximum speed limit of 55 in an inequality?

Back

s ≤ 55, where s is the speed.

Front

What is the first step to solve the inequality: 11x + 14 < -8?

Back

Subtract 14 from both sides: 11x < -22.

If Johnny earns $15 per hour and wants to earn at least $105, what inequality represents this situation?

Back

15h ≥ 105, where h is the number of hours worked.

Front

What is the solution to the inequality: 3x - 5 > 4?

Back

Add 5 to both sides: 3x > 9, then divide by 3: x > 3.

Front

What does it mean if a solution to an inequality is represented on a number line?

Back

It shows all the possible values that satisfy the inequality.
