Solving One Step Inequalities Challenge

What symbol is used in a solution set for inequalities?

• Equal sign

• Multiplication sign

• Plus sign

• Inequality symbol

What is the result of subtracting 2 from both sides of the inequality 'n + 2 ≤ 5'?

• n ≥ 3

• n = 3

• n ≤ 7

• n ≤ 3

How do you verify the solution of an inequality?

• Substitute boundary values

• Multiply by zero

• None of the above

• Add random values

What does adding 3 to both sides of 'y - 3 > 9' result in?

• y > 12

• y < 12

• y = 12

• y > 6

Why do we use an open dot when graphing 'y > 12'?

• To exclude 12

• To indicate division

• To include 12

• None of the above

What happens to the inequality symbol when multiplying or dividing by a positive number?

• It disappears

• It becomes an equal sign

• It remains the same

• It reverses

What is the solution when you divide both sides of '10x < 80' by 10?

• x < 8

• x > 8

• x = 8

• x ≤ 8

How do you check if 'x < 8' is a correct solution?

• x = 10

• x = 6

• x = 8

• x = 9

What is the result of multiplying both sides of 'x/6 ≥ 7' by 6?

• x > 42

• x ≥ 42

• x = 42

• x ≤ 42

Why might you choose a number divisible by 6 to test the inequality 'x ≥ 42'?

• Easier calculation

• Higher accuracy

• Smaller numbers

• None of the above
