Answer:
153,000 is your answer.
Step-by-step explanation:
{-2x+y=12 => y=12+2x
{3x+2y=38
3x+2(12+2x)=38
3x+24+4x=38 /-24
7x=14 /:7
x=2
y=12+2*2=12+4=16
y=16
<em>Solution: (2; 16)</em>

Point B is the answer......
The length of the pool is 28 meters and the width of the pool is 10.5 meters.
In the scale drawing of Joe, the community pool has (length : width) = 8 : 3
Let the actual length of the pool is 8x meters and the actual width is 3x meters.
Now, given that the actual pool has a perimeter of 77 meters.
So, 2(8x + 3x) = 77
⇒ 22x = 77
⇒ x = 3.5
So, the length of the pool is 8x = 8(3.5) = 28 meters and the width of the pool is 3x = 3(3.5) = 10.5 meters. (Answer)
