  • (2,4)

And

  • x-y=2

Both and tell why pls……..

Answer:

4) A

5) E

Step-by-step explanation:

#4

\frac{x}{y}=\frac{1}{10} * \frac{z}{y}

\frac{x}{y} =\frac{1z}{10y}

Cross multiply the equation and you get:

10xy=zy

Since \frac{a}{b}=\frac{c}{d}  is the same thing as ad=bc, you can change the equation into \frac{x}{z} =\frac{y}{10y}

Cancel out the y on the top and bottom and you get 1/10

#5

\frac{2}{3} *\frac{x}{2} =5, simplify and you get \frac{x}{3} =5 so x=15

\frac{1}{5} * 3(x) is equal to \frac{1}{5} *3(15) after you plug in x, and that is equal to 9
