Hi, could anyone get the answer for this one?
\(\displaystyle 0.7\, \sqrt{100\, -\, p\,} \, +\, 0.3\, \sqrt{36\, -\, p\, +\, B\,}\, -\, 1\, =\, \overline{u}\, =\, 7.8\)
\(\displaystyle 0.7\, \sqrt{100\, -\, p\,} \, +\, 0.3\, \sqrt{36\, -\, p\, +\, B\,}\, -\, 1\, =\, 0.3\, \sqrt{100\, -\, p\,}\, +\, 0.7\, \sqrt{36\, -\, p\, +\, B\,}\)
Basic algebra yields \(\displaystyle p\, \approx\, 8.8,\, B\, \approx\, 22.5\)
It would be great if you provide steps, I just cant get the answer the teacher gave us...
Many thanks!
