The value of k is 60
131 - 11 = 120
120/2 = 60
hope this helped !

seperable differential equations will have the form

what you do from here is isolate all the y terms on one side and all the X terms on the other

just divided G(y) to both sides and multiply dx to both sides
then integrate both sides

once you integrate, you will have a constant. use the initial value condition to solve for the constant, then try to isolate x or y if the question asks for it
In your problem,

so all you need to integrate is
120138 subtract both and that would be the answer
Answer:
55 Rs.
Step-by-step explanation:
cost of the milk:
15.5 x 30 = 465 Rs.
Gross sales of the milk:
26 x 20 = 520 Rs.
Profit:
520 - 465 = 55 Rs.
The answer is 25
1/5 of 45 is 9, so you have 36 tickets
then half of 36 is 18
then you add the 7 tickets Danny won
18+7=25
