y=40
a line is 180 degrees and the other side is 70 that means 110 =2y+x so x=30 then you fill in the x. 2y+30=110 you subtract 30 from 110 and get 80 then divide 80 by 2 and get 40
Answer:
Ending Amount = beginning amount / 2^n where "n" is the number of half-lives or elapsed time / half-life
For this problem "n" = 25 / 11 = 2.2727272727
Ending Amount = 60 grams / 2^2.2727272
Ending Amount = 60 / 4.832357534
Ending Amount = 12.4162998242 grams
