Solve for x over the real numbers using factor method:
10 x^2 + 19 x - 15 = 0
The left hand side factors into a product with two terms:
(2 x + 5) (5 x - 3) = 0
Split into two equations:
2 x + 5 = 0 or 5 x - 3 = 0
Subtract 5 from both sides:
2 x = -5 or 5 x - 3 = 0
Divide both sides by 2:
x = -5/2 or 5 x - 3 = 0
Add 3 to both sides:
x = -5/2 or 5 x = 3
Divide both sides by 5:
Answer: x = -5/2 or x = 3/5
C = 2pi*r
Plug in the circumference
6.28 = 2*pi*r
3.14 = pi *r
plug in pi
3.14 = 3.14 * r
r = 1

Answer:
The Total Capacity per bus is 53 people.
Step-by-step explanation:
To work this out you would first minus 8 from the total to find out how many actually went on the bus, and so we do not count the people walking. Then as you know there are six busses you would divide that new total by 6 to find the capacity per bus.
1) Minus 8 from 326.
2) Divide that by 6.
3) Total capacity.
The Total Capacity per bus is 53 people.
This shows that the total capacity per each bus is 53 people.
