Answer:
32
Step-by-step explanation:
The problem above can be solved by using the <em>multiplication operation</em>. 
Given: 400 people
            8% of the people with green eyes
Let's solve:
Let x be<em><u> the number of people with green eyes.</u></em>
x = 400 x 8%
x = 400 x (0.08)
x = 32
So, the number of people surveyed with green eyes is 32. The rest of the surveyed people (368) have a different eye color.
 
        
             
        
        
        
5x + 10           10
---------- =      -------
   121               11
make the bottom have same common denominator
10/11 x (10/10) = 100/121
Get rid of the denominator (for both now have 121 as a base)
5x + 10 = 100
5x + 10 (-10) = 100 (-10)
5x = 90
5x/5 = 90/5
x = 18
x = 18  is your answer
hope this helps
