1)down 8 up 10
2)11.2
3)9+9+9+9+9=45
4)middle
5)77.0
The equation has one solution, x = -7.
X^2 + x(x - 5) - x + 7
x^2 + x^2 - 5x - x + 7
2x^2 - 6x + 7
$21.6

Step-by-step explanation:
Kilometres when Satish is alone
150 kilometres in the beginning
150 kilometres in the end
Total: 300 kilometres
Litres of gas when Satish is alone
