A.) You multiply the meal price with .18 (converting the fraction to decimal).
B.) After that, you add the meal price with answer of A
You need to convert gallons to ounces. 1 gallon = 128 fluid ounces. So to find the price of an 8 ounce glass of Moo Milk you need multiply 8/128 x 5.12. That equals $0.32.
Answer:
-55.1
Step-by-step explanation:
2x + 553x - 10
-2x -2x
551x - 10
/551 /551
x = -55.1
Okay. So when you solve 864/31 on a sheet of paper and you divide it properly, the remainder you get should be 27. The answer is B: 27.

Answer: 10 feet</h3>
===================================================
How to get this answer:
A pentagon has 5 sides. If each side is the same length, then each side is 20/5 = 4 feet long. That halves to 4/2 = 2 feet. Each side is now 2 feet long, and there are 5 total sides, so 2*5 = 10 feet is the new perimeter.
A shortcut is to simply divide the perimeter in half to get 20/2 = 10. The reason why this works is because the perimeter is the sum of all the sides, which are all being cut in half.
-----
Algebraically, if we had the five sides a,b,c,d,e then
P = a+b+c+d+e
is the perimeter
Cutting each side in half gives
0.5*a+0.5*b+0.5*c+0.5*d+0.5*e = 0.5*(a+b+c+d+e) = 0.5*P
showing that we've cut the perimeter in half.
