They would have used a total of 30 horses. Each person would've each ridden 15 so 15+15= 30 and 165 divided by 11 is 15. Hope this is off help!
Answer:
4 2/7
Step-by-step explanation:
- x * 9 4/5 = 42
- x * 49/5 = 42
- x = 42 : 49/5
- x = 42 * 5/49
- x = 30 /7
- x = 4 2/7
First, multiply both sides by y to get rid of that y in the denominator.
![y(\frac{3}{2} y)= y( \frac{16}{y} + 2) ](https://tex.z-dn.net/?f=%20y%28%5Cfrac%7B3%7D%7B2%7D%20y%29%3D%20y%28%20%5Cfrac%7B16%7D%7By%7D%20%2B%202%29%0A)
![\frac{3}{2}y^2= 16+2y](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B2%7Dy%5E2%3D%2016%2B2y%20)
Then, rearrange it to put it into standard form so you can easily see the values for a, b, and c.
![\frac{3}{2}y^2 +2y +16=0](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7Dy%5E2%20%2B2y%20%2B16%3D0)
Plug into quadratic formula, and you get this result:
![y= \frac{2+/- \sqrt{100} }{3}](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B2%2B%2F-%20%5Csqrt%7B100%7D%20%7D%7B3%7D%20)
So, y=4, y=8/3
Answer:
x=3, C
Step-by-step explanation:
X is less than 4.
Just simplify each side and solve for the variable.
First add 9 to both sides.
24 is greater than 6x
Then divide 6
4 is less than 6
