Answer:
n = 6.30
Step-by-step explanation:
-5n+2.75 -2.75= -28.75 - 2.75
-5n =-31.50
divide both sides by -5
-5n/-5 = -31.50/ -5

Answer:
Absolute: 39 pounds
Relative: 6.5%
Step-by-step explanation:
To find the absolute difference, we simply have to see by how much pounds the estimation was off.
The real measure was 639 pounds, the estimated weight was 600.
D = 639 - 600 = 39 pounds.
For the percent of error, we divide the absolute difference (39) by the real value (639) and we'll get the % of error. So,
%D = 39 / 600 = 0.0610, so 6.1%
We don't need to round it to the nearest tenth, since it's already to that precision level.
