The equations y=55x+50 and y=65x represents Rick's and Betty's trip.
Step-by-step explanation:
Given,
Head start of Rick = 50 miles
Speed of Rick = 55 mph
Let,
x be the number of hours
y be the total miles
Distance covered by Rick in x hours = Speed * Time + Head start
y = 55x + 50
Speed of Betty = 65 mph
Total miles = Speed*Time
y=65x
The equations y=55x+50 and y=65x represents Rick's and Betty's trip.

prime (not composite) as it can only be divided by 1 and itself
Step-by-step explanation:
3x-47=65
3x=65+47
3x=112
x=37.3
2 hours because 65 miles is = to one hour
130=65x2
130 miles is =to 2 hours
