The correct set of numbers is:
2. 3, 4, 6, 7
We can plug each of these numbers into the inequality 18 + 2x ≥ 36 to see if they are all solutions:
For x = 3: 18 + 2(3) = 18 + 6 = 24, which is not greater than or equal to 36. So 3 is not a solution.
For x = 4: 18 + 2(4) = 18 + 8 = 26, which is not greater than or equal to 36. So 4 is not a solution.
For x = 6: 18 + 2(6) = 18 + 12 = 30, which is not greater than or equal to 36. So 6 is not a solution.
For x = 7: 18 + 2(7) = 18 + 14 = 32, which is not greater than or equal to 36. So 7 is not a solution.
Therefore, none of the numbers in this set are solutions to the inequality.
In which of the given sets of numbers are all the numbers solutions of 18 + 2x ≥ 36 ?
