I hope it helps you. please mark me brainliest answer.
Answer:
2y=8-x
y-2x=-1
y-2x=-1
y = 2x-1
Substitute for y in the 1st
2(2x-1)=8-x
4x-2=8-x
5x = 10
x = 2
y=2x-1
y = 3
Explanation:
2y=8-x
y-2x=-1
------------
Rearrange:
x = 8-2y
y = 2x-1
------------
Substitute to get:
y = 2(8-2y)-1
y = 16-4y-1
5y = 15
y = 3
-------------------
Substitute to solve for "x":
x = 8-2(3)
x = 2

your answer is B
It's hard for me to explain this but the only difference between the two is that the independent variable in the controlled group stays constant so you can see the difference in results between the experimental and controlled group
You measure the paper you are using to draw the map on and you measure the size of the country you are putting on your paper, then you can calculate the measurements and divide by how much states can fit in on your paper.
