Answer:
A
Step-by-step explanation:
(5y+6y)+(4x+8y)+(1z-5y)=
5y+6y+4x+8y+1z-5y=
14y+4x+1z
Melissa combined unlike terms
25x+30x= 1625
x+y= 60
Put into calculator and you get
x=35 y=25
The time of your arrival should be 12:30 PM
8:00 AM departure+2 hours elapsed=10:00 AM
10:00 AM+30 minute lunch=10:30 AM
10:30 AM+1 hour=11:30 AM
11:30 AM+15 minute gas stop=11:45 AM
11:45 AM+45 minutes driving time=12:30 PM time of arrival
