Answer:
The solution is the point (18,0)
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system by substitution
substitute equation B in equation A
![\frac{1}{3}x-6=-\frac{1}{3}x+6](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dx-6%3D-%5Cfrac%7B1%7D%7B3%7Dx%2B6)
solve for x
Adds (1/3)x both sides
![\frac{1}{3}x-6+\frac{1}{3}x=6](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7Dx-6%2B%5Cfrac%7B1%7D%7B3%7Dx%3D6)
![\frac{2}{3}x-6=6](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7Dx-6%3D6)
Adds 6 both sides
![\frac{2}{3}x=6+6](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7Dx%3D6%2B6)
![\frac{2}{3}x=12](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7Dx%3D12)
![x=12(3)/2\\x=18](https://tex.z-dn.net/?f=x%3D12%283%29%2F2%5C%5Cx%3D18)
<em>Find the value of y</em>
substitute the value of x in equation A or equation B
![y=-\frac{1}{3}(18)+6=0](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B1%7D%7B3%7D%2818%29%2B6%3D0)
therefore
The solution is the point (18,0)
1/3 of 24hr is 33.33333333 repeating
To find that take 19 divided by 25 = .76 or 76%
Answer:
254
Step-by-step explanation:
x-39=215
215+39=x
215+39=254
