Answer:
We have the following given
mileage = 70 miles per gallon
distance = 60 km
Required: amount of fuel in gallons
First, we must convert the distance to miles, so
60 km (1 mi/1.6 km) = 37.5 mi
So, the amount of fuel is
37.5 mi / (70 mi/gal) = 0.54 gallon
Answer:
(f+g)(x) = 4 x^2 + (3/2) x - 7
Answer (c) on your list
Step-by-step explanation:
f+g (x) = f(x) + g(x) = x/2 - 3 + 4 x^2 + x - 4
combine the terms in "x" = x/2 + x = (3/2)x
combine the numerical terms: - 3 - 4 = - 7
Then the final expression is:
(f+g)(x) = 4 x^2 + (3/2) x - 7
