If x=4(3-y)(2^2-1), what is the value of y in terms of x?

hello there...

x = 4(3-y)(4-1)

x =( 12 - 4y )(3)

x = 36 - 12y

-12y = 36+x

y = (36+x)/(-12)

y = -(36+x)/12 or y = (-36-x)/12

AND WE ARE DONE <3

y=3-x/12

Step-by-step explanation:

x=4(3-y)(2^2-1)

x=4(3-y)(4-1)

x=3*4(3-y)

x=12(3-y)

x/12=3-y

y=3-x/12

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

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
