step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
