alina1380 [7]

Answer: 37.92

Step-by-step explanation: We know that 3202 / 5 = 640.4.

We subtract that by 830 to get (830 - 640.4  =) 189.6. Then we do / by five again to get 37.92. That is the answer.

hoa [83]
\bf ~~~~~~~~~~~~\textit{internal division of a line segment}
\\\\\\
A(-9,5)\qquad B(15,-11)\qquad
\qquad \stackrel{\textit{ratio from A to B}}{7:1}
\\\\\\
\cfrac{A\underline{p}}{\underline{p} B} = \cfrac{7}{1}\implies \cfrac{A}{B} = \cfrac{7}{1}\implies 1A=7B\implies 1(-9,5)=7(15,-11)\\\\
-------------------------------

\bf p=\left(\cfrac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \cfrac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)\\\\
-------------------------------\\\\
p=\left(\cfrac{(1\cdot -9)+(7\cdot 15)}{7+1}\quad ,\quad \cfrac{(1\cdot 5)+(7\cdot -11)}{7+1}\right)
\\\\\\
p=\left(\cfrac{-9+105}{8}~~,~~\cfrac{5-77}{8}  \right)\implies p=\left( \cfrac{96}{8}~~,~~\cfrac{-72}{8} \right)
\\\\\\
p=(12~,~-9)
