Answer:
A car is more fuel efficient and it goes 30 miles per gallon (5/12 gallon to travel 12 1/2 miles)
Step-by-step explanation:
A car : 5/12 gallon to travel 12 1/2 miles
(12 1/2) / (5/12) =
(25/2) / (5/12) =
25/2 * 12/5 =
150/5 =
30 miles per gallon
B car : 5/7 gallon to travel 20 5/7 miles
(20 5/7) / (5/7) =
(145/7) / (5/7) =
145/7 * 7/5 =
145/5 =
29 miles per gallon
most fuel efficient is A car....it gets 30 miles per gallon
Answer:
See the three answers with their explanation below
Explanation:
<u>a. To eliminate the fraction from each side you multiply both sides by the least common denominator of the fractions of the two sides.</u>
In this case it is 2×3 = 6
See how you do it:

<u>b. This word problem would lead to the given equation:</u>
Half the age of Alice 4 years ago equals 2 more than one third of her current age.
- Current age: x
- Age four years ago: x - 4
- Half the age of Alice four years ago:

- 2 more than one third of her current age:

Equality condition:
<u>c. Solution</u>

Meaning: Alice is currently 24 years old.
Answer = a) add them
