Answer:
A). [tex]y=x-\frac{2}{5}[/tex]
B). y = [tex]1.8\bar{3}x[/tex]
Step-by-step explanation:
Question (1)
A). If every block of the given figure represents [tex]\frac{1}{5}[/tex],
Measure of x = [tex]\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}[/tex]
= 1
Measure of y = [tex]\frac{1}{5}+\frac{1}{5}+\frac{1}{5}[/tex]
= [tex]\frac{3}{5}[/tex]
Since, [tex]\frac{2}{5}=1-\frac{3}{5}[/tex]
[tex]\frac{2}{5}=x-y[/tex]
[tex]y=x-\frac{2}{5}[/tex]
Therefore, there is a decrease of [tex]\frac{2}{5}[/tex].
B). Measure of each box = [tex]\frac{1}{11}[/tex]
y = [tex]11\times \frac{1}{11}[/tex]
x = [tex]6\times \frac{1}{11}[/tex]
[tex]\frac{y}{x}=\frac{11\times \frac{1}{11}}{6\times \frac{1}{11} }[/tex]
[tex]\frac{y}{x}=\frac{11}{6}[/tex]
[tex]y=\frac{11}{6}x[/tex]
y = [tex]1.8\bar{3}x[/tex]
