The answer is 27. if you take the clues given in the question, the equation for the length will be ‘2w+5’. add all of the w’s for width around and the constants and your equation will the become 6w+10=76. after you find the width, plug it into ‘2w+5’ and you will get your length.
Answer:
78
Step-by-step explanation:
You take the original total: 60, and multiply it by 30 to get 1,800. You then divide 1,800 by 100 to get 18. 18 is your 30%. Now, you add the 30% to 60 getting your total number of ducks: 78.
The equation version:

It is just proportions.

Quick Review:
By doing the inverse of 7/12, 12/7, when you multiply it, you'll get a value of 1.
7/12 * 12/7 = 1
Doing the Problem:
By multiplying 5 1/4 by 12/7, you'll get the answer. But first, convert 5 1/4 into an improper fraction.
5 1/4 ---> 21/4
Okay, lets go!
21/4 * 12/7 = 252/28
<u>When reduced, this gives you the answer 9/1, or 9 gallons.</u>
Hope that helps, :)
