2. -$40 + 100 = $60 - $50 = $10
Cindy currently has $10 left in her bank account.
Answer:
x = 8 and y = 10
Step-by-step explanation:
Since the figures are congruent:
Angle PQR = EFG
6y + x = 68
Segment QR = FG
2x - 4 = 12
Solving that:
2x - 4 = 12
2x = 16
x = 8
Replacing x in 6y + x =68
6y + 8 = 68
6y = 60
y = 10
You would divide 7 by 4. (7/4) each section would be 1.75 miles :)
