The inequality 18 + 2x ≥ 36 can be solved by subtracting 18 from both sides: 2x ≥ 18. Then by dividing both sides by 2: x ≥ 9.
In the set of numbers {10, 5, 8}, only 10 is greater than or equal to 9, so it is the only solution to the inequality.
Therefore, the set of numbers in which all the numbers are solutions of 18 + 2x ≥ 36 is {10}.
In which of the given sets of numbers are all the numbers solutions of 18+2x≥36 ?
