Answer:
A construction crew has just finished building a road. The crew worked for 5 5/6 days. how many kilometers long, how many kilometers of road did they build each day? (Assume they built the same amount each day.) hope this helps ; )
Step-by-step explanation:
A + b = 15 ..... eq 1
a – b = 12 ...... eq 2
So a = 15 – b
Substitute in eq 2 :
15 – b – b = 12
15 – 2b = 12
–2b = 12 – 15
b = 1.5
So a = 15 – 3/2 = 13.5
4ab = 4 x 13.5 x 1.5 = 81
