David should buy Car A because it covers more miles in one gallon than Car B
Step-by-step explanation:
Given
Distance traveled by Car A = 
Gallons used by Car A = 
Distance traveled by Car B = 
Gallons used by Car B = 
In order to find the distance traveled on one gallon, we will divide the total distance by number of gallons
So,
Distance traveled by Car A in one gallon = 
Distance traveled by Car B in one gallon = 
We can see that Car A travels more distance in one gallon that is 58.5 miles per gallon
So,
David should buy Car A because it covers more miles in one gallon than Car B

<h3>The measurement of 3.08 cm has
3 significant digits in it .</h3>
We say this because a measurement is considered significant if it has non zero numbers in it , which 3.08 cm has . And a measurement is considered a significant digit if it has zero between it's non zero digits . Hence we say that 3.08 cm has 3 significant digits .

Hey there! I'm happy to help!
Let's represent Ben's age with a B and Jeff's with a J in a few equations below.
B=J-9 (Ben is 9 years younger than Jeff)
B+10+J+10=67 (In 10 years, the sum of their ages will be 67)
We know that B is equal to J-9. So, in the second equation, we can replace B with J-9 to solve for J.
J-9+10+J+10=67
We combine like terms.
2J+11=67
We subtract 11 from both sides.
2J=56
We divide both sides by two.
J=28
And, we know that Ben is nine years younger than Jeff, so this means Ben is 19 years old.
Ben is 19 years old and Jeff is 28.
I hope that this helps! Have a wonderful day! :D
Answer:
Step-by-step explanation:
Perimeter= 2L+2W. If L=3W(three times the width) then 2(3W)+2W=112. Or 6W+2W=112 which is equal to 8W=112. To solve for the width, divide both sides by 8 and find 112/8=14, therefore W=14.
