The area (A) of the sector is

A = area of circle × fraction of circle

please help me and explain. what is the value of <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7By%7D%20" id="TexFormula1"

rosijanka [135]

$\frac{28}{x^2} = \frac{7}{xy}$
multiplying both sides by x^2
$28=\frac{7x^2}{xy}$
simplifying
$28= \frac{7x}{y}$
dividing by 7
$\frac{28}{7}= \frac{x}{y}$

Help on this question please!!!

OLga [1]

Answer:

Hello! Here is your answer

Step-by-step explanation:

112=4(28)

a=4b

You can only have one variable so:

Combine b to a:

a-b=84

4b-b=84

Divide both sides by 3:

3b/3=84/3

b=28

But that is not it:

Sum of both cards:

a+b

a=112

b=28

112+28=140

= 140

I hope I was of help. If not please let me know! Thank you! Good luck!
