Answer 2

Alright, let's break this down step by step. First, let's substitute the value of $a$ into the expression:

$$(13a - 7a + 5 - a) \times 0.5$$

Now, simplify the expression:

$$(5) \times 0.5$$

Finally, calculate the result:

$$2.5$$

So, when $a = 0.5$, the expression evaluates to $2.5$. I hope that helps!
