13x+23x= -72
36x= -72
x= -2
<h2>
Half Life</h2>
The half life period is the time in which only half of the given population remains. It can be represented through this equation:

- <em>t</em> = time passed
- <em>a</em> = y-intercept
- <em>h</em> = half life
<h2>Solving the Question</h2>
We're given:
- <em>h</em> = 28 million years
- <em>a</em> = 184 grams (this is the initial mass, after 0 time has passed)
For most questions like this, we would have to plug these values into the equation mentioned above. However, this question asks for the time elapsed after 3 half-lives.
This can be calculated simply by multiplying the given half-life by 3:
28 million years x 3
= 84 million years
<h2>Answer</h2>
84 million years
Four hundred two million seventy-three thousand one hundred eighty in standard form: 402,073,180 would be your answer
