hillary had 8 pieces
john had 6 pieces
 
        
             
        
        
        
A + b + c + 180
-a
b + c = 180 - a
-b
c = 180 - a - b
        
             
        
        
        
Answer:
81
Step-by-step explanation:
let the terms be a,ar,ar²
r=2/3
a+a(2/3)+a(2/3)²=171
multiply by 9
9a+6a+4a=171×9
19 a=171×9
a=(171×9)/(19)
a=9×9=81
 
        
                    
             
        
        
        
A) c=18
0.5c^2 +13=94
subtract 13 from both sides
0.5c^2 = 81 
Square root of both sides to get c alone 
0.5c=9
double c to make it just c
c=18
B) x=8
(x-2)^2+1=37
Subtract one from each side
(x-2)^2=36
square root each side 
x-2=6
add the 2 over 
x=8
