Answer:
$18.56
Step-by-step explanation:
Since we know that distance between Oban and Stranraer is 178.9 miles.
Let us find the number of gallons of fuel used during the journey by dividing total distance traveled by distance traveled per gallon of fuel.
Now let us find the total cost of fuel for the journey by multiplying number of gallons of fuel used by cost of per gallon fuel ($0.83).
Therefore, the journey will cost $18.56 in fuel.
Answer:Answer:
−78+−12=−138
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(-7/8, -1/2) = 8
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(−78×11)+(−12×44)=?
Complete the multiplication and the equation becomes
−78+−48=?
The two fractions now have like denominators so you can add the numerators.
Then:
−7+−48=−118
This fraction cannot be reduced.
The fraction
−118
is the same as
−11÷8
Convert to a mixed number using
long division for -11 ÷ 8 = -1R3, so
−118=−138
Therefore:
−78+−12=−138
Solution by Formulas
Apply the fractions formula for addition, to
−78+−12
and solve
(−7×2)+(−1×8)8×2
=−14+−816
=−2216
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(22,16) = 2
−22÷216÷2=−118
Convert to a mixed number using
long division for -11 ÷ 8 = -1R3, so
−118=−138
Therefore:
−78+−12=−138
