The inequality is 18 + 2x ≥ 36.
Subtracting 18 from both sides, we get:
2x ≥ 18
Dividing both sides by 2, we get:
x ≥ 9
So any number greater than or equal to 9 is a solution to the inequality.
Out of the given sets of numbers, the set that contains all numbers greater than or equal to 9 is:
{9, 10, 11, 12, 13}
Therefore, the answer is: {9, 10, 11, 12, 13}.
Which of the given sets of numbers are all the numbers solutions of 18 + 2 x ≥ 36?
