Simple....
you have:
-12+5k=15-4k
isolate the variable...
-12+5k=15-4k
+12 +12
5k=27-4k
5k=27-4k
+4k +4k
9k=27
k=3
Thus, your answer.

Answer:
a) 7.78 months
b) 1116
Step-by-step explanation:
Given -

Integrating the above equation with respect to time, we get -

let us define new variable x

substituting these values in above integral equation, we get -


at t = 0, P (0) = 1075, using this condition, we get -

9x and 5x are "like terms."
9x - 5x produces the same result as does -5x + 9x.
83.041 in notation form is 80+3+.04+.001
