The set in which all numbers are solutions of 18 + 2x ≥ 36 is:
9, 10, 11, 12
For this set:
18 + 2(9) = 18 + 18 = 36
18 + 2(10) = 18 + 20 = 38
18 + 2(11) = 18 + 22 = 40
18 + 2(12) = 18 + 24 = 42
All the numbers in this set satisfy the inequality.
In which of the given sets of numbers are all the numbers solutions of 18 + 2x ≥ 36
9, 10, 11, 12
9, 8, 7, 6
8, 7, 6
0, 3, 9, 12
