Answer:
   16
Step-by-step explanation:
If we take the partial image to be 1/2 of a full image, then there are a total of 
   5 1/2 + 2 + 6 + 2 1/2 = 16
acorn images on the graph. Each image represents 4 acorns, so a total of ...
   4 × 16 = 64
acorns are represented on the graph. Since these are ones the squirrels ate, the remaining 80 -64 = 16 acorns were left uneaten.
 
        
             
        
        
        
Hey there! :D
The midpoint and the outside line are symmetrical to eachother, 2(BF)= AE
Two midpoint segments equals one AE segment. 
So, use the representation above and plug in the numbers. 
2(23)= 5x -4
56= 5x-4
Add 4 to both sides. 
60=5x
Divide by the 5. 
x=12 
I hope this helps!
