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.

Answer:
-5/2x+3
Step-by-step explanation:
you reciprocate the slope since you are trying to find a line perpendicular.
From this m=2/5 to -5/2
then use the formula y-y1 =m(x-x1)
then you put in the points
y - - 2= -5/2(x- 2)
y+2= -5/2x +5
-2 -2
y= -5/2+ 3

Answer:
x=-1
Step-by-step explanation:
-2x - 5 = -3
add 5 to both sides
-2x = 2
divide both sides by -2
x = -1
