Please explain how to find the answer

irina1246 [14]

Answer:

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

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

Step-by-step explanation:

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

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

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

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

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

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

┈

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

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

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

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

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

┈

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

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

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

Mrs. King has 3 3/4 yards of fabric she uses 1 7/8 yards to create a blanket and 1/2 yard to make a pillow.how much fabric does

Mashcka [7]

Total number of fabric Mrs. King has = $3\frac{3}{4} yards$

Number of yards of fabric used for a blanket = $1\frac{7}{8} yards$

Number of yards of fabric used to make a pillow = $\frac{1}{2} yards$

To find the number of yards of fabrics Mrs. King has left, we apply the operations of Addition and Subtraction

Step 1 : Addition Operation

Total number of fabrics used by Mrs. King = Fabric used for blanket + Fabric used for pillow

$1\frac{7}{8} yards + \frac{1}{2} yards$

= $2\frac{3}{8} yards$

Step 2 : Subtraction Operation

Total number of yards of fabric left = Total number of fabrics - Total number of fabrics used

$3\frac{3}{4} yards - 2\frac{3}{8} yards$

= $1\frac{3}{8} yards$
