Answer:
A. 8 gallons
B. Drive by car is $59.4 cheaper than travel by train
Step-by-step explanation:
According to the scenario, given data are as follows,
Total drive = 400 miles
Total drive per gallon = 50 miles
Fuel cost per gallon = $4.45
A. So, Total fuel required to drive 400 miles can be calculated as follows,
Total fuel required = Total drive ÷ Total drive per gallon
By putting value, we get,
Total fuel required = 400 ÷ 50
= 8 gallons
B. Total cost if drive by car = 8 gallons × $4.45 = $35.6
Cost if travel by train = $95
Hence it is clearly shows that drive by car is much cheaper than travel by train.
Cost saved by travel by car = $95 - $35.6 = $59.4
So, drive by car is $59.4 cheaper than travel by train.

Answer:
(-18, 14), (-9, 9), (9, -1), (18, -6)
Step-by-step explanation:
Since there is a 9 in the denominator of the coefficient of x, we will get integer solutions only if x is a multiple of 9. Suitable values meeting the problem requirements are x ∈ {-18, -9, 9, 18}. Then the corresponding values of y are ...
y = -5/9(-18) +4 = 10 +4 = 14
y = -5/9(-9) +4 = 5 +4 = 9
y = -5/9(9) +4 = -5 +4 = -1
y = -5/9(18) +4 = -10 +4 = -6
The four solutions we have found are ...
(-18, 14), (-9, 9), (9, -1), (18, -6)
