Answer:
15,008 grams
Step-by-step explanation:
You have 30,016 grams of radioactive kind of rubidium. How much will be left after 54 minutes if its half-life is 18 minutes? 15,008 grams.
-(1/2)p<-16
Divide both sides by the coefficient of p. Flip the inequality sign because you are dividing a negative number.
p>32
Final answer: A
Subtract 36 from both sides making it: -4c-3c=-14
Now subtract -4c and 3c making it: -7c=-14
Now divide by -7 on both sides making it: c=2
There you go
