A) blue/total = (3+2)/(8+2) = 5/10 = 50%
b) blue/total = (3)/(8 +2) = 3/10 = 30%
        
             
        
        
        
Answer:
y = 39
Step-by-step explanation:
550 x  =
 =  
  x 11 + y
 x 11 + y
550 x  =
 =  x 11 x 11 + y
 x 11 x 11 + y
550 x  x
 x  = 11 x 11 + y
 = 11 x 11 + y
550 = 11 x 11 + y
 =
 =  x 11 + y
 x 11 + y
50 = 11 + y
50 - 11 = y
39 = y
