Question

For which inequality would x = 4.5 not be a solution?

8x ÷ 5 > 0
9x - 5 < 80
x + 6 ≥ 10
12 - x ≥ 8

Answer 1

Answer: Hello, the answer is 12 - x ≥ 8.

Reasoning: Since you would plug in the value of x with 4.5, each problem would have a correct answer except for the last one, which would be:

12 - (4.5) ≥ 8.

12 - 4.5 = 7.5.

7.5 is not greater than or equal to 8.

Hope it helped.
