Question

A + B + C + D + E + F + G + H + I + J = 76.5

Answer 1

The solutions will be a 9 dimensional plane of \(R^{10}\) spanned by the vectors <1,0,0,0,0,0,0,0,0,75.5>, <0,1,0,0,0,0,0,0,0,75.5>, <0,0,1,0,0,0,0,0,0,75.5>, <0,0,0,1,0,0,0,0,0,75.5>, <0,0,0,0,1,0,0,0,0,75.5>, <0,0,0,0,0,1,0,0,0,75.5>,
<0,0,0,0,0,0,1,0,0,75.5>, <0,0,0,0,0,0,0,1,0,75.5>, <0,0,0,0,0,0,0,0,1,75.5>.

Answer 2

thx polpak btw i am srry for giving her the answer

Answer 3

It's ok, I'm not really upset. I was explaining more for your benefit than for hers as it was clear she was just going to keep asking more questions. It will just make you a better tutor if you can walk them through the process of solving the problem rather than doing it for them.

Answer 4

yup
