Salt flows in at a rate of (5 g/L)*(3 L/min) = 15 g/min.
Salt flows out at a rate of (x/10 g/L)*(3 L/min) = 3x/10 g/min.
So the net flow rate of salt, given by in grams, is governed by the differential equation,
which is linear. Move the term to the right side, then multiply both sides by :
Integrate both sides, then solve for :
Since the tank starts with 5 g of salt at time , we have
The time it takes for the tank to hold 20 g of salt is such that
Answer:
the answer is C.
Step-by-step explanation:
if you divide 10 divided by 2 it gives you 5 and then subtract it by 2.2 = 2.8
there goes your answer.
Answer:
8x + 2y
Step-by-step explanation:
You need to use distributive property.
5(x + y)
5 · x = 5x
5 · y = 5y
3(x - y)
3 · x = 3x
3 · -y = -3y (don't forget the sign)
So,
5x + 5y + 3x - 3y
Arrange them,
5x + 3x + 5y - 3y
Simplify,
5x + 3x = 8x
5y - 3y = 2y
So,
8x + 2y
