The EPA says the value of a human life is $7.6 million, measured from birth to death. If life expectancy is 78 years, what is th
UkoKoshka [18]
The value would be $2.53 million.

Set up a proportion to solve this:

7.6/78 = x/(78-52)

[7.6 million for 78 years; x million for 78-52 years remaining]

Cross multiply:
7.6(78-52) = x*78
7.6(26) = 78x
197.6 = 78x

Divide both sides by 78:
197.6/78 = 78x/78
2.53 = x

Segment addition with variables
oksian1 [2.3K]

<em>x equals 22</em>

<h2>Explanation:</h2>

____________________________________________

The Segment Postulate states the following:

<em>Given two end points A and B, a third point C lines on the segment AB if and only if the distances between the points satisfy the equation:</em>

\overline{AB}=\overline{AC}+\overline{CB}

____________________________________________

From the figure:

\overline{AC}=8+x \\ \\ \overline{CB}=10 \\ \\ \overline{AB}=40

Our goal is to find x:

\overline{AB}=\overline{AC}+\overline{CB} \\ \\ Substituting \ values: \\ \\ 40=(8+x)+10 \\ \\ 18+x=40 \\ \\ Subtracting \ 18 \ from \ both \ sides: \\ \\ 18-18+x=40-18 \\ \\ \boxed{x=22}
