Answer:

C

Step-by-step explanation:

3 - [tex]\frac{x}{2}[/tex] ≥ 12 ( subtract 3 from both sides )

- [tex]\frac{x}{2}[/tex] ≥ 9 ( multiply both sides by 2 to clear the fraction )

- x ≥ 18

multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative quantity

x ≤ - 18
