Answer:
12.8 servings
Step-by-step explanation:
cups of milk is used to make 10 servings of a recipe.
If cups or 
cups of milk is used to to make 1 serving.
Then 1 cup of milk will be required to make servings = 
= 
Since, 1 gallon = 16 cups
Therefore, 16 cups of milk will be required for servings = 
= 12.8 servings
I know you can create an equation to solve this but its been a while since ive done this so im going to slowly write it out.
Day-1=12
2=18
3=24
4=30
5=36
6=42
7=48
8=54
9=60*
n=9
Y is the function of x so there are two things called Input and output
Since y=x+3 (given)
Put value of y in equation x+y=(-3)
x+x+3=(-3)
2x=(-6)
x=(-3)
Put x=(-3) in x+y=(-3)
(-3)+y=(-3)
y=0
So, x=(-3)
y=0
