Answer:
the ratio is 12:7 but im not 100% sure
To calculate the remaining caffeine, we use the radioactive decay formula which is expressed as An = Aoe^-kt where An is the amount left after t time, Ao is the initial amount and k is a constant we can calculate from the half-life information. We do as follows:
at half-life,
ln 1/2 = -k(6)
k = 0.12/hr
An = 80e^-0.12(14)
An = 15.87 mg
x+5= 10
move +5 to the other side
sign changes from +5 to -5
x+5-5= 10-5
x= 10-5
x= 5
Answer:
x= 5
Answer:
2(x-1)=2x-2
