Answer:
A) -15, 5, 2
Step-by-step explanation:
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.
Our first expression is
. Upon distributing the exponent 4 on all the terms, we get:

Therefore, your answer is correct for this part. :)
Second expression is
. Upon distributing the exponent -2 on all the terms, we get:

Your second answer is correct too.
Our third expression is
. Upon distributing the exponent 2 on all the terms, we get:

This one is not correct. Your answer would have been correct, if the exponent were -2 instead of 2 in this part.
Our forth and last expression is
. Upon distributing the exponent -5 on all the terms inside the parenthesis, we get:

Therefore, your answer for this part is also correct.
Looking at your work, I don't think you made a mistake in number 3 also, probably mis-typed the question while writing here :)
Answer:
30/100 X $60= $18.
The original price will be $60 + $18 = $78.
