Answer:
440 miles.
Step-by-step explanation:
A rental company charges for rent a truck = $75 per day
and the charges per mile = 20 cents
100 cents = 1 dollar
20 cents =
= $0.20
Michael rents a truck for 2 days.
Let Michael drove the truck in 2 days = x miles
and his bill came to $238.
the equation will be : (75 × 2) + 0.20x = 238
150 + 0.20x = 238
0.20x = 238 - 150
0.20x = 88
x =
x = 440
Michael drove the truck 440 miles in 2 days.

We know that
(ad)/(bd)=d/d time a/b=a/b since d's cancel
also
if a/b=c/d in simplest form, then a=c and b=d
we have
p/(x^2-5x+6)=(x+4)/(x-2)
therefor
p/(x^2-5x+6)=d/d times (x+4)/(x-2)
p/(x^2-5x+6)=d(x+4)/d(x-2)
therefor
p=d(x+4) and
x^2-5x+6=d(x-2)
we can solve last one
factor
(x-6)(x+1)=d(x-2)
divide both sides by (x-2)
[(x-6)(x+1)]/(x-2)=d
sub
p=d(x+4)
p=([(x-6)(x+1)]/(x-2))(x+4)
