Answer:
11 3/4 miles.
Step-by-step explanation:
Converting to improper fractions, the consecutive distances are:
21/4 , 55/8, 17/2
= 42/8, 55/8, 68/8 for Monday, Tuesday and Wednesday.
So the distances have increased by 13/8 miles each day.
Thus number of miles he'll bike on Friday = 68/8 + 2(13/8)
= 94/8
= 11 3/4 miles.
5p + 9c = p
9c = p - 5p
9c = -4p
c = -4p/9
c=
y = 7.25x + 18
18 is the base. so it goes last.
7.25 is the amount being raised per a certain amount (hours) so its 7.25x
