A 33 gram sample has k value of .1124
(Actually I think the problem SHOULD be worded: A 33 gram sample has k value of -.1124/days)
See attached graphic:
Half-Life = ln (.5) / k
Half-Life = -.693147 / -.1124/days
Half-Life =

Adam is incorrect because if you substitute the value of y (which is 2) on the expression 52-3y=20, the statement is false since 46 is obviously not equal to 20.
52-3(2)=20
52-6=20
46 = 20
FALSE
<span>-17-2x=6-x
-2x + x = 6 + 17
-x = 23
x = -23</span>
