Answer:
First is not a part. second is a part
Step-by-step explanation:
So, what you want to do in this question is plug the value of k=8 into the inequality and see if it is still true.
For the first one,
5(8)<39
40<39, which is not true
For the second one,
8/2 ≤ 4
4≤ 4, which is true
Quantity of gasoline needed by a car to run 800 miles = 30 gallons
Quantity of gasoline needed by a car to run 1 mile =
= 30 ÷ 800
= 0.0375 gallons
So , to run 1 mile a car would need = 0.0375 gallons of oil
To run 700 miles the quantity of gasoline needed =
= 700 × 0.0375
= 26.25 gallons of gasoline
Therefore , a car will use 26.25 gallons of gasoline on a trip of 700 miles .
Answer:
