It should take 4 years, please mark me brainliest it would mean a lot and if you want an explanation, Comment and I’ll help you out
Answer:
a. 
b. 
c. 
Step-by-step explanation:
a. The volume of water initially in the fish tank = 15 liters
The volume of brine added per minute = 5 liters per minute
The rate at which the mixture is drained = 5 liters per minute
The amount of salt in the fish tank after t minutes = x
Where the volume of water with x grams of salt = 15 liters
dx = (5·c - 5·c/3)×dt = 20/3·c = 

b. The amount of salt, x after t minutes is given by the relation




c. Given that in 10 minutes, the amount of salt in the tank = 25 grams, and the volume is 15 liters, we have;




I would use is over of equals percent over 100 is woudl be 120% and of would be 75 then you would put x over 75
Answer:

Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Linear equations are typically organized in slope-intercept form:
where m is the slope and b is the y-intercept (the value of y when x is 0) - Parallel lines always have the same slopes
<u>1) Determine the slope (m)</u>

The given line has a slope of -2. Because parallel lines always have equal slopes, we know that the line parallel to this would also have a slope of -2. Plug this into
:

<u>2) Determine the y-intercept (b)</u>

Plug in the given point (2,4) to solve for b

Add 4 to both sides to isolate b

Therefore, the y-intercept of the line is 8. Plug this back into
:

I hope this helps!
