Answer:

or

Step-by-step explanation:
The expression  can be simplified by first writing the fraction under one single radical instead of two.
 can be simplified by first writing the fraction under one single radical instead of two.

5/15 simplifies because both share the same factor 5.
It becomes 
This can simplify further by breaking apart the radical.

A radical cannot be left in the denominator, so rationalize it by multiplying by √3 to numerator and denominator.

 
        
             
        
        
        
Answer:
y = 15x+32
Step-by-step explanation:
Given 
y to be the total minutes Andrew will play video games today
x is the total number of games played after school
If he wants to play an additional 15 minutes each of x games after school today, the total minutes he will use for the x games will be 15* x = (15x)minutes
We are told that he has initially spent 32minutes on video games. hence;
Total minutes Andrew used on games y = (15*x)+32
The required equation will be y = 15x+32

X and 67° are supplementary (they equal 180) so to find x you do 180-67 which equals 113. So x=113°
