Answer:
Step-by-step explanation:
1l ........8.5 miles
x l .......6 miles
-----------------------
x=6*1/8.5
x=0.70 l
2*0.7=1.4 l petrol/day ( to work and come back home)
5*1.4=7 l/week ( 5 days works in a week)
7*1.26=8.82 L /week
8.82>8.5
The petrol costs more
So the answer is NO
2) longest line is (-1, -3) and (-1, 7)
3) (-1, -3), (-6,2), and (2,4)
Answer 0.06*0.7+0.03=0.072 and 0.06*(-0.2)+0.03=0.018
