The amount in gallons of each milk containing 9% butterfat and milk containing 4% butterfat which must be used to obtain the desired 365 gallons are;
- 219 gallons of 9% fat.
- 146 gallons of 7% fat.
<h3>What quantity of each type of milk is required for the desired 365 gallon?</h3>
It follows from the task content that the quantity of each type of milk required to arrive at the targeted fat content and quantity of milk are to be determined.
Let x = quantity of 9% fat milk and
Let y = quantity of 4% fat milk
Therefore, by mass balance; we have;
x + y = 365.
Where; y = 365 - x.
Also, by fat balance; we have;
(9% × x) + (4% × y) = (7% × 365)
9x + 4y = 2555
Therefore, the two equations to be solved simultaneously by substituting y from the first equation into the second equation as follows;
9x + 4 (365 - x) = 2555
5x = 1095
x = 1095/5
x = 219 gallons.
Also, y = 365 - 219 = 146 gallons.

The answer to 1+1 is 2. hope this helps you
Answer:
many solutions
Step-by-step explanation:
You have to attribute values to x, and then you find the y value.
The x value you attributed and the y value you got as a result will be an ordered pair of the linear equation
For example:
x = 4
y = 3*4-7
y = 5
(4 | 5) is an ordered pair.
x = 3
y = 3*5-7
y = 8
(3 | 8) is another one.
