Answer:
Hey there!
We can write this equation, where x is the hourly rate and y is the fixed fee.
4x+y=270
7x+y=420
4x+y=270
-7x-y=-420
-3x=-150
x=50
4(50)+y=270
200+y=270
y=70.
The fixed fee is G. $70.
Let me know if this helps :)
42 because it is y = (x - 1) * 1 + 6.
y is the total cost, and x is the amount of visits - 1 because of the six dollar one.

Answer: 12 mph
Step-by-step explanation:
20 minutes = 1/3 hour
Distance = speed x time
D = 27 x 1/3 = 09 miles
He had taken 45 minutes when he drove home
45 minutes = 3/4 hour
Speed = distance / time
Speed = 9 / 3/4
Speed = 12 mph
