5. because I found it. hahaha
Answer:
15.9
Step-by-step explanation:
The question above may be solved using the overall mass and component balances. If we let x be the number of liters of peroxide that should be added, the final mixture will have a quantity of x+12 L. The peroxide balance before and after mixing is,
x(1) + 12(0.08) = (x + 12)(0.16)
The value of x is 1.143. Thus, approximately 1.143 L of peroxide should be added to the original solution.
The point-slope form of a line:

We have the points (-9, -5) and (2, -4). Substitute:

The standard form of a line:

<em>multiply both sides by 11</em>

<em>subtract 9 from both sides</em>
<em>subtract 11y from both sides</em>
