Determine the number of miles driven on the highway and on the city
Represent the gallons used on highway with h and on city with c.
So, we have:
---- gallons used
and
--- distance travelled
In the first equation, make c the subject

Substitute 10 - h for c in the second equation


Open bracket

Collect like terms


Make h the subject


Substitute 5 for h in 


If on the highway, he travels 31 miles per gallon, then his distance on the highway is:


If in the highway, he travels 26 miles per gallon, then his distance on the highway is:


Answer:
there cannot be any solution of the given linear equation.
Step-by-step explanation:
i) the linear equation of 18x +
= 6(3x + 25)
ii) transforming the equation to a simpler form we get
18x +
= 18x + 150 which implies that
= 150 which is not true.
iii) therefore there cannot be any solution of the given linear equation.
Step-by-step explanation:
6x + 120y + 6x2
Final answer
Product means multiply so 2,681 times 4 = 10,724
