The cylinder and sphere !!!!
Add, -11.5x and move it over to 8.5x
Then, subtract them together and you get 20x + 51.86 = 51.76
And you move (subtract) 51. 86 over to 51.76, subtract that and you get 20x = -0.1
Divide, and your answer is -200
Day = 24 hours, right?
36000/24 = 1500
If I put this into words:
36000 people per 24 hours = 1500 people per 1 hour
On average, 1500 people ride the bus per hour (or each hour)
You use the quadratic formula:
2x {}^{2} - 3x = 5
2x {}^{2} - 3x - 5 = 0
x = \frac{3 + - \sqrt{9 -4(2)( - 5)}}{2 \times 2}
x = \frac{3 + - \sqrt{49} }{4}
x = \frac{3 + 7}{4} \: and \: x = \frac{3 - 7}{4}
x = \frac{5}{2} \: and \: x = - 1
That's easy you just need to listen in school to answer it
