<em>Answer:</em>
<em>y = - 5 ; x = 6</em>
<em>Step-by-step explanation:</em>
<em>-5y+4x= 49</em>
<em>7y+2x= -23 | × - 2</em>
<em />
<em>-5y+4x= 49</em>
<em>-14y - 4x = 46</em>
<em>___________ +</em>
<em>- 5y - 14y + 4x - 4x = 49 + 46</em>
<em>- 19y = 95 | × - 1</em>
<em>19y = - 95</em>
<em>y = - 95 : 19</em>
<em>y = - 5</em>
<em />
<em>- 5(-5) + 4x = 49</em>
<em>25 + 4x = 49</em>
<em>4x = 49 - 25</em>
<em>4x = 24</em>
<em>x = 24 : 4</em>
<em>x = 6</em>
You divide 3600/20,ad you will get 180 square feet.
Answer: The area is 5024 yrd^2
Step-by-step explanation:
80 is the diameter to we need to divide it by 2 to find the radius
80/2= 40
A= 3.14* 40^2
A = 3.14 * 1600
A= 5024
Here you go... please note the values are different on your y axis ☺️
