100 circles and another 100 circles and 76 circles.
Draw in real life it will work.
Another way 2 hundreds 7 tens and 6 ones
        
                    
             
        
        
        
<span>2x + 5 =8x
6x = 5
x = 5/6
12x = 12(5/6) = 10</span>
        
                    
             
        
        
        
Answer:
b) 

Step-by-step explanation:
b) set up equations so they are equal to each other,



this is when f(x)=g(x) so our approximation was close.
c)solving it graphically is nearly impossible because the solution can be any value around the intersection. only way to be sure is to solve it symbolically.
