what is the solution set for $16.5 geq 1.25x + 12.75$?\na $x leq -3$\nb $x geq -3$\nc $x geq 3$\nd $x leq 3$

Explanation:

Step1: Subtract (12.75) from both sides

$$16.5 - 12.75\geq1.25x+12.75 - 12.75$$ $$3.75\geq1.25x$$

Step2: Divide both sides by (1.25)

$$\frac{3.75}{1.25}\geq\frac{1.25x}{1.25}$$ $$3\geq x$$ which can be written as (x\leq3)

Answer:

D. (x\leq3)
