Depends on what you are asking
Y = Mx + c
Finding the equation of the line
Which is y = -3x + 8
Or for finding y
Y = 8-3x
Or if u wanna find x
You subtract y from both sides
3x = 8 - y
Dividing both sides by 3
3x/3 = 8/3 -y/3
Which leave 8 -y divided by 3

<em>The perimeter is c. 28 millimeters</em>
Step-by-step explanation:
<u>The Perimeter of a Square</u>
The perimeter of a square is the sum of all its side lengths. If the side length is L, then the perimeter is:
P = 4L
The diagonal of a square is the hypotenuse of a right triangle with both legs of length L.
Applying Pythagora's theorem, we find the length of the diagonal is:
![D=\sqrt{2}L](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B2%7DL)
We know the diagonal of a square is
![D=7\sqrt{2}](https://tex.z-dn.net/?f=D%3D7%5Csqrt%7B2%7D)
We can find the side length L:
![\sqrt{2}L=7\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7DL%3D7%5Csqrt%7B2%7D)
Simplifying:
L = 7 millimeters
Thus, the perimeter is:
P = 4*7 = 28
The perimeter is c. 28 millimeters

Answer:
3 3/5
Step-by-step explanation:
You can change 4/1 into 20/5 (equivalent fraction), then you can do 20-2 to get 18. So 18/5 can also be 3 3/5
