Answer:
$3.60
Step-by-step explanation:
First divide the total cost by how many cartons of milk there are multiplied by how many gallons there are in a carton. So it would look like 28.80/4*2 which is 3.6
Answer: x ≈ 6.86°
Step-by-step explanation:
Firstly, set them equal to each other:
(7x + 24) = 72°
Subtract 24 from both sides:
7x = 48°
Divide both sides by 7:
x ≈ 6.857...
This can be rounded to:
x ≈ 6.86°
Substitute x = 3 in any given equations. I will do in y = - x + 1
Therefore the answer is (3,-2)
We can write the question as a mathematical formula as follows:
1000 * 0.08 = m * 0.05 + c * 0.2
1000 = m + c
where m are pints of milk and c are pints of cream
So solving the first equation with m = 1000 - c
1000*0.08 = (1000-c)*0.05 + c*0.2
80 = 50 - 0.05c + 0.2c
80-50 = (0.2-0.05)*c
30 = 0.15*c
c = 30/0.15
c = 200
m = 1000-200 = 800
So the dairy needs 800 pints of milk and 200 pints of cream
