Element X decays radioactively with a half life of 15 minutes. If there are 230 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to
decay to 33 grams?
y = a(.5)

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)

it is impossible.
