K(x) = 5x-6
(k+k)(x) = k(x) + k(x) = 5x-6 +5x-6
simply substitute x = 4,[ [TAG_3]](k+k)(4) = 5(4) -6 + 5(4) -6
that will be your answer, the last option.

Driving from oban to stranraer a driver averages 8 miles per gallon of fuel. if fuel costs 83 cents a gallon how much will be th

Svet_ta [12734]

Answer:

$18.56

Detailed solution:

The given distance from Oban to Stranraer is 178.9 miles.

First, determine the gallons of fuel consumed by dividing this distance by the vehicle's mileage (miles per gallon).

$\text{Total number of gallons of fuel used during the journey}=\frac{178.9\text{ miles}}{8\frac{\text{miles}}{\text{gallon}}}$

$\text{Total number of gallons of fuel used during the journey}=\frac{178.9\text{ miles}}{8}\times \frac{\text{gallon}}{\text{miles}}$

$\text{Total number of gallons of fuel used during the journey}=22.3625\text{gallon}$

Next, calculate the total fuel expense by multiplying the amount of fuel used by the price per gallon, which is $0.83.

$\text{Total cost in fuel during the journey}=22.3625\times\$0.83$

$\text{Total cost in fuel during the journey}=\$18.560875\approx \$18.56$

Hence, the total fuel cost for this trip amounts to $18.56.
