Step-by-step explanation:
-We calculate the margin of errors for both Judy and Atticus:
We realize that Judy's assumed value was nearer to the eal value than Atticus'.

Answer:
D) x = -7.5
Step-by-step explanation:
x + 8 = 0.5
Subtract 8 from each side
x+8-8 = .5 -8
x = -7.5
Is it supposed to say 7x rather than Z? If so then
If you make both equations = to 4y you can work out the answer so
4y =7x-4
4y = 36-3x
Then you put them equal to each other so
7x-4 = 36-3x
10x = 40
x = 4
You can then find y by doing
4y = 7x4 - 4
4y = 28-4
4y = 24
y= 6
So the answer is x = 4 and y = 6
The correct ones are A,B, D&E
