20 gallons
Step-by-step explanation:
Divide 120 miles by 8 to find miles per gallon
120 ÷ 8 = 15 miles per gallon
Now divide 300 miles by 15 to find number of gallons required
300 ÷ 15 = 20
20 gallons are required for a journey of 300 miles
Answer:
pairs of numbers is 3,-3
Step-by-step explanation:
The computation is shown below:
Let us assume a and b are the pairs of the numbers whose difference is 6
i.e.
a - b = 6
a = 6 + b
So
f = ab
f = (6 + b)b is minimum
Now
d ÷ db (6+ b)b = 0
(6+ b) + b = 0
2b = -6
b = -3
Now
a = 6 + b
= 3
So pairs of numbers is 3,-3
