Given
A + B = 8
A + C = 13
B + D = 8
C - D = 6
Now
A + B = B + D
A = B + D -B
A = D
C - D = C - A
A + C = 13
C - A = 6
Adding 7 on both sides
C - A +7 = 6+7
C - A + 7 = A + C
C-C -A + 7 = A
-A +7 = A
7 = A+A
7/2 = A
A = 3.5
B = 4.5
C =9.5
D = 3.5

Answer:
The greatest possible error for the measurement 3.2 cm is 0.05 cm.
Step-by-step explanation:
Given : Bruce measured a buckle as 3.2 cm using the ruler
To find : What is the greatest possible error?
Solution :
The greatest possible error in a measurement is half of the measuring unit.
Measurement 3.2 cm.
3.2 was measured to the nearest tenth of a cm or 0.1 cm
So the measuring unit is 0.1.
The GPE is half of 0.1
i.e, ![\frac{0.1}{2}=0.05](https://tex.z-dn.net/?f=%5Cfrac%7B0.1%7D%7B2%7D%3D0.05)
Therefore, The greatest possible error for the measurement 3.2 cm is 0.05 cm.
