Answer: The value of x is 6. The measure of angle B is 20 degrees.
Step-by-step explanation:
3x + 2 + 55 = 13x- 3
3x + 57 = 13x -3
-3x -3x
57 = 10x -3
+3 +3
60= 10x
x= 6
3(6) +2 = m∠B
20= m∠B
Think of dividing by 2 splitting it in half, if you round it you get about 1500 then split that in half. it would be around 750.
Answer:
Step-by-step explanation:
Initial Quantity of salt Q(0) = 100 kg
Capacity of tank = 1000 L
Inflow of liquid = 10 l /minute and outflow = same rate thus leaving the content of volume 1000 L at any time
Assume after entering constantly mixes and drains out.
Concentration flow = inflow - outflow
= 0.05(10) - 
i.e.
, Q(0) = 100

Use Q(0) = 5
-45 = A
So the equation would be

a) Initial concentratin = 
b) Use the solution fo rDE substitute t =1
Q(1) = 50-45e^(-0.01) = 5.4477 kg
c) As t becomes large Q = 50
So concentration limit = 50/1000 = 0.05
