Answer:
x = 1 and y = -2
Step-by-step explanation:
Given that,
2x-3y = 8 ..(1)
4x+3y = -2 ..(2)
Add equation (1) and (2),
2x-3y+4x+3y = 8+(-2)
6x = 6
x = 1
Put the value of x in equation (1).
2-3y = 8
2-8 = 3y
-6 = 3y
y = -2
Hence, the value of x is 1 and that of y is -2.
Yes! For example, 10 and 20 have 1, 2, 5, & 10 in common ^.^
Answer:
The perimeter is 1280ft
Step-by-step explanation:
Let the side length of the square be s.
Then the distance around three sides is 3s.
According to the question the distance around 3 sides of a square city block is 960 feet.
This implies that:
![3s = 960](https://tex.z-dn.net/?f=3s%20%3D%20960)
![s = \frac{960}{3}](https://tex.z-dn.net/?f=s%20%3D%20%20%5Cfrac%7B960%7D%7B3%7D%20)
![s = 320](https://tex.z-dn.net/?f=s%20%3D%20320)
The perimeter of a square is
![p = 4s](https://tex.z-dn.net/?f=p%20%3D%204s)
Substitute s=320 to get:
![p = 4(320)](https://tex.z-dn.net/?f=p%20%3D%204%28320%29)
![p = 1280](https://tex.z-dn.net/?f=p%20%3D%201280)
The perimeter is 1280 ft
