7/12 of the punch was left.
There is 12/12 (whole) of the punch Dave is holding, then when he spills 5/12, that is 12/12 - 5/12 which equals 7/12. Did this help?
Answer:
![x=-3,13](https://tex.z-dn.net/?f=x%3D-3%2C13)
Step-by-step explanation:
Given: ![x^2-10x=39](https://tex.z-dn.net/?f=x%5E2-10x%3D39)
To find: solutions of the given equation
Solution:
![x^2-10x=39\\x^2-10x-39=0](https://tex.z-dn.net/?f=x%5E2-10x%3D39%5C%5Cx%5E2-10x-39%3D0)
Write ![-10=-13+3](https://tex.z-dn.net/?f=-10%3D-13%2B3)
Therefore,
![x^2-13x+3x-39=0\\x(x-13)+3(x-13)=0\\(x+3)(x-13)=0\\x=-3,13](https://tex.z-dn.net/?f=x%5E2-13x%2B3x-39%3D0%5C%5Cx%28x-13%29%2B3%28x-13%29%3D0%5C%5C%28x%2B3%29%28x-13%29%3D0%5C%5Cx%3D-3%2C13)
So, solutions of the given equation are
and
