In the inequality 3x - 2 ≥ 12, what is the result when x = 5?

• 12

• 13

• 14

• 11

• Yes, because 13 is greater than or equal to 12

• No, because 13 is less than 12

• Yes, because 13 is less than 12

• No, because 13 is not greater than or equal to 12

What should you do after substituting the value of x in the inequality 3x - 2 ≥ 12?

• Add the numbers

• Divide the numbers

• Subtract the numbers
