Answer:
39.43 for each dog
Step-by-step explanation:
<u>d = 2c (given) </u>
164 c + 23 d = 4140 sub in the above equation for d
164 c + 23<u> (2c)</u> = 4140
210c = 4140
c =19.71
d = 2c = 39.43
So the punch has 2 liters of ginger ale. 2 liters of ginger ale is 20 percent of the punch. The punch has 8 liters of cranberry juice, 2 liters of ginger ale.
P=2g + 80
P is punch, g is ginger ale
b) 8 liters
The formula for the area of a rectangle is:
![A=wl](https://tex.z-dn.net/?f=A%3Dwl)
w = width
l = length
First, we have to convert 2
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
into an improper fraction, then into a number. The improper fraction would be
![\frac{5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B2%7D%20)
. Let's convert that into a decimal.
![5/2=2.5](https://tex.z-dn.net/?f=5%2F2%3D2.5)
Let's multiply
![2.5*10=25](https://tex.z-dn.net/?f=2.5%2A10%3D25)
The area of the rectangle would be 25 feet!
D because a straight line is 180 degrees. Since 2x+15 and 65 add up to a straight line (180 degrees) in the picture, the answer is D.
