I believe that the answer is there is 1 thirds in 1/3 I hope this helps
Answer: x=4 and BC=20
STEPS:
Set the equation for AC and DF equal to each other then solve for x.
2x+7=5x-5
Eliminate the -5 by adding it to both sides.
2x+12=5x
Move the x to one side by subtracting 2x from both sides.
12=3x
Isolate the x by dividing both sides by 3
4=x
EF=5x which means BC=5x
5(4)= 20
So BC= 20
