This is described by Choice D:
The second equation in System 2 is the difference of the equations in System 1. The first equation in System 2 is the first equation in System 1.
That is exactly 8 half lives.
After 8 half - lives only (1 / 2^8) or (1 / 256) of the original 30 grams will remain.
(1 / 256) =

Answer:
x = 
Step-by-step explanation:
Given
3x + k = c ( isolate the term 3x by subtracting k from both sides )
3x = c - k ( divide both sides by 3 )
x =
