Answer:
Hi there!
Your answer is:
To get from step 3 to step 4, Lloyd added 36 to both sides. On the left side, this equaled 0 due to the additive inverse property! (-36 + 36 = 0!) On the right side, 36 is added to 216! (216+36 = 252)
The difference in the widths, in meters, of the human hair and the piece of sand is
m.
It is given in the question that:-
Width of a human hair =
m
Width of a piece of sand =
m
We have to find the difference in the widths, in meters, of the human hair and the piece of sand.
We know that,
Difference between the widths = Width of a piece of sand - Width of a human hair
Hence, we can write,
Difference between the widths =
m -
m
We can write,

Hence,
Difference between the widths =
m
