<span>The rounded result is
4,000. If you just write "4,000", though, it's not clear whether there
are 1, 2, 3 or 4 significant figures, since trailing zeroes could be
significant (or not). For that reason, scientific notation is often
used. 4 × 10³ has one significant digit, 4.0 × 10³ has two, 4.00 × 10³
has three, and so on.
So, use either 4,000 or 4 × 10³, depending on what your teacher expects.</span>
N is a variable in algebra. Variables are letters that represent unknown numbers. Variables can be any letter of the alphabet.
Here's how to use n in an algebraic equation:
5 + n = 12
To find what N represents, let it be the only thing on the left side of the variable:
5 -5 + n = 12 - 5
n = 7

Answer:
B. 10 1/2 feet
Step-by-step explanation:
We are told that she taped 7 boxes.
We are also told that she uses 1 1/2 feet of tape to close each box.
Therefore, the length of tape she will need to use for the 7 boxes will be the product of 7 boxes and 1 1/2 feet of tape per box:
L = 1 1/2 * 7 = 3/2 * 7 = 21/2 = 10 1/2 feet.
She will need to use 10 1/2 feet of tape.
