Please explain how to find the answer
irina1246 [14]

Answer:

\rm x=\frac{46}{3}

\rm y=-\frac{25}{24}

Step-by-step explanation:

\huge\begin{array} {|c|} \hline\left. \begin{cases} {   \rm\frac{ 1  }{ 4  }  x+ \frac{ 4  }{ 5  }  y =  3  } \\ {   \rm\frac{ 5  }{ 16  }  x- \frac{ 1  }{ 5  }  y=5  }  \end{cases} \right. \\  \hline \end{array}

\\ \Large \overline{ \rm -   \: Steps \:  using  \: substitution \: - }

\rm \frac{1}{4}x+\frac{4}{5}y=3

\rm \frac{1}{4}x=-\frac{4}{5}y+3

\rm x=4\left(-\frac{4}{5}y+3\right)

\rm x=-\frac{16}{5}y+12

┈

\rm \frac{5}{16}\left(-\frac{16}{5}y+12\right)-\frac{1}{5}y=5

\rm -y+\frac{15}{4}-\frac{1}{5}y=5

\rm -\frac{6}{5}y+\frac{15}{4}=5

\rm -\frac{6}{5}y=\frac{5}{4}

\bold{ y=-\frac{25}{24}}

┈

\rm x=-\frac{16}{5}\left(-\frac{25}{24}\right)+12

\rm x=\frac{10}{3}+12

\bold{ x=\frac{46}{3}}

Wewaii [24]

Answer:

256 cm^2

Step-by-step explanation:

2 of triangulars can be together to become a new square.

because these 2 triangulars have a symmetric shape.

So the all area is 10×16 (the square in the center) + (6×16)

All area is 160 + 96

= 256 cm^2

* the formular of the square area is the width × the length
