Answer:
In the year 2000 the number of hazardous waste sites in state y was 21
Step-by-step explanation:
Let
x ----> the number of hazardous waste sites in state x in the year 2000
y ----> the number of hazardous waste sites in state y in the year 2000
we know that
----> equation A
----> equation B
Solve the system of equations by substitution
Substitute equation B in equation A
![34=2y-8](https://tex.z-dn.net/?f=34%3D2y-8)
Solve for y
Adds 8 both sides
![34+8=2y](https://tex.z-dn.net/?f=34%2B8%3D2y)
![42=2y](https://tex.z-dn.net/?f=42%3D2y)
Divide by 2 both sides
![y=21](https://tex.z-dn.net/?f=y%3D21)
therefore
In the year 2000 the number of hazardous waste sites in state y was 21
You can indeed use similar triangles to get a side of another similar triangle.
let's say Edwardo stood next to the building and his shadow was 20ft, he's 4ft tall, and the building cast a shadow of 125ft, then, check the picture below.
Length=18ft
