Answer:84
Step-by-step explanation:because 7x12=84
It should be D: 35. 14 + 6 = 20. I just multiplied that by two, which equals 40. That means there are 2 sets of 14 and 2 sets of 6. Since there is 10 leftover, I divided both by 2. 7 + 3 = 10. 14 x 2 = 28 + 7 = 35
1/3(1/2)8(6)(10)=80

Answer:

Step-by-step explanation:
Given
Rate = 130.16 miles for 5 gallons
Required
Number of gallons used for a journey of 60 miles
The rate in miles per gallon is calculated as:

When distance = 130.16 and gallons = 5, we have:


When distance = 60 miles.
Substitute 60 for distance and 26.032 for rate in 

Cross Multiply
