Question

1. which expression is equivalent to $\frac{1}{2}(13f + 5)$?

6.5f 2.5
6.5f + 5
36f
9f

Explanation:

Step1: Apply distributive property

$\frac{1}{2}(13f + 5)=\frac{1}{2}\times13f+\frac{1}{2}\times5$

Step2: Calculate each term

$\frac{1}{2}\times13f = 6.5f$ and $\frac{1}{2}\times5=2.5$, so the result is $6.5f + 2.5$

Answer:

$6.5f + 2.5$
