Pretty sure this is wrong but I got,
$77,184,751.5431
The next step would be 10n=5x-7+9-x

The answer is 48 degrees because you add 42 and 90 and then subtract from 180 (total degrees of a triangle)
Mark reads about 350 (D) wpm
Explanation:
700 words x 10 pages= 7000 words
7000 words/ 20 minutes
= 350 wpm
X^2/(x- 9 = 81/(x - 9)
This is the equation for which you want the solution.
Multiplying both sides of the equation by (x - 9) we get
x^2(x - 9)/(x - 9) = 81(x - 9)/(x - 9)
So the (x - 9) goes out from both the denominator and the numerator and then the simplified equation becomes
x^2 = 81
x ^2 = (9)^2
x = 9
So the value of the unknown variable x comes out to be 9.
