Answer:
x+19
Step-by-step explanation:
3x+12 - 2x+7 = x+19
88.83 / 21 = 4.23
4.23 is the same number as 423% .
8.23 is <em>423%</em> of 21.
So, 0.5^5 is 0.03125
multiply that by 125 and get your answer.
*3.90625* (4)
just saying, I got the 0.5^5 thing because 5 is the number of half-lives (x) and 0.5 is the rate of loss (or whatever its called).
If it were to gain, you would put 1.5
186 if that’s the answer you where looking for if not comment here it will give me a notification and I will see
Divide the previous value by 5.
