Use simultaneous equations:
2x + 7 = x^2 + 8x - 9
7 = x^2 + 6x - 9
16 = x^2 + 6x
+ or - 4 = 7x
answer is
-4/7 or 4/7

Answer:
$156.35
Step-by-step explanation:
we know that
A group of friends went to lunch, and their bill was $132.50
In this problem
$132.50 represent the 100%
100%+18%=118%
so
using proportion
Find out the total amount that represent 118%
Let
x ----> the total amount of the bill
![\frac{\$132.50}{100\%}=\frac{x}{118\%}\\\\x=132.50(118)/100\\\\x=\$156.35](https://tex.z-dn.net/?f=%5Cfrac%7B%5C%24132.50%7D%7B100%5C%25%7D%3D%5Cfrac%7Bx%7D%7B118%5C%25%7D%5C%5C%5C%5Cx%3D132.50%28118%29%2F100%5C%5C%5C%5Cx%3D%5C%24156.35)
To solve this problem, you first have to add the total miles driven.
2000 + 20 = 2020
Then, you have to convert miles into feet. There are 5280 feet in a mile, so you multiply that by 2020.
5280 * 2020 = 10665600
Therefore, the total feet driven is 10665600. I hope this helped, good luck!
