• Understanding geometric shapes

• Solving two-step inequalities

• Multiplication and division equations

• Graphing linear equations

What mathematical method is used to solve two-step inequalities as described in the video?

• Addition and subtraction first, then multiplication and division

• Only addition and subtraction

• Using exponents and roots

In the example given, if 3m + 10 = 24, what is the value of m?

• m < 8

• m < 12

• m < 16

• m < 4

What happens to the inequality sign when you multiply both sides of an inequality by a negative number?

• It becomes an equality

• It reverses

• It remains the same

• It disappears

How is the inequality for the carnival budget scenario set up?

• Total cost ≤ $40

• Total rides ≥ 12

• Total rides ≤ 12

• Total cost ≥ $40

What does the inequality 'r ≤ 12' signify in the context of the carnival?

• Rashaan cannot enter the carnival

• Rashaan can spend more than $12

• Rashaan must ride more than 12 rides

• Rashaan can ride at most 12 rides

What is the correct inequality for the situation where Leigh wants to buy burgers without exceeding her budget?

• b ≥ 4

• b ≤ 4

• b = 4

• b ≠ 4

What is the maximum number of burgers Lee can buy if each costs $3 and she has $12?

• 5 burgers

• 4 burgers

• 6 burgers

• 3 burgers

If Chevron sells gasoline for $3 per gallon and a car wash costs $8, what is the inequality for keeping the total purchase under $45?

• 3g + 8 < 45

• 3g + 8 ≤ 45

• 3g + 8 ≥ 45

• 3g + 8 > 45

Which value of g makes the inequality 3g + 8 < 45 true when g = 11?

• Irrelevant to the inequality

• True

• False

• Cannot be determined
