Answer 1

Answer:

$13$

Step-by-step explanation:

The given expression is;

$3x-2$

We want to evaluate this expression when $x=5$.

This means that, we substitute $5$ wherever we see $x$ in $3x-2$

The expression will now be

$=3(5)-2$

This will simplify to be

$=15-2$

The final result is

$=13$

The correct answer C.
