Answer 1

 "At least 13 years" means more or equal 13,
so 
x ≥ 13.

Answer 2

Answer:

$a\geq 13$

Step-by-step explanation:

A PG-13 movie rating means that your age, a, must be at least 13 years for you to watch the movie.

Let the age be represented by 'a'

The inequality that will form will be :

$a\geq 13$

At least 13 years means not minimum than 13. So, the sign will be greater than or equal to 13, denoting that a minimum of 13 years is needed.
