The answer would be 4,000
Answer:
2.57
Step-by-step explanation:
You first have to multiply the -5.3 times the -1.9. Once you do that, you get 10.07. Then, you add the -7.5.
Here are the equation steps:
(-7.5) + (-5.3)x(-1.9)
(-7.5) + (10.07)
2.57
Answer:
128 servings can be made using 1 gallon of milk.
Step-by-step explanation:
Given that:
cups of milk make 10 servings
can also be written as 1.25
Ratio of cups of milk to servings = 1.25 : 10
1 gallon = 16 cups
Let,
x be the number of servings made from 1 gallon
Ratio of cups of milk to servings = 16 : x
This is a direct proportion
1.25 : 10 :: 16 : x
Product of mean = Product of extreme
10*16 = 1.25x
160 = 1.25x
1.25x=160
Dividing both sides by 1.25

Hence,
128 servings can be made using 1 gallon of milk.
