We we are asked to solve this kind of problem we are asked to find the value of the value (x in this case). So the first thing we want to do isolate x by subtracting 5/12 from both sides.
x+5/12-5/12=5/8-5/12
Simplify
x=5/8-5/12
Reduce
x=3/3(5/8)-2/2(5/12)
x=15/24-10/24
x=5/24
200$ because if you do 2000dovided by 10 then it will equal=200 so loook 200x10=2000 so 1/10=200
There will be a 25 grams left after 3240 years.
The half-life of Radium-226 is 1620 years. If we divide 3240 by 1620 the answer is 2. So that means the amount of Radium-226 will divide in half twice.
100 / 2 = 50 / 2 = 25
Answers D. and E. are correct.
I think that B might also be correct, I hope This helps.
