Solve for x. show each step of the solution.
2.5(6-2x)+11=104-1.5(6x+12)

Step-by-step explanation:

we have

Distribute in both sides

Combine like terms in both sides

group terms that contain the same variable

Adds 9x both sides

Subtract 26 both sides

Divide by 4 both sides

8987678

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
