A 6 foot wide painting should be center on a 14 foot wide wall. how many feet X should be on each side of the painting
serious [3.7K]

Answer:

4 feet

Step-by-step explanation:

We start by subtracting the 6 from the 14, to get the leftover space on the wall, 8 feet. We then divide that by two, since if the painting is centered there will be two equally-sized spaces on either side of it. This means that X = 4 feet.

How many times greater is 9 x 10^12 than 3 x 10^6
Harrizon [31]
<h3>Answer:   3 x 10^6</h3>

This is the number 3,000,000 aka 3 million

=======================================================

To find this answer, we divide the two values (large/small)

(9 x 10^12)/(3 x 10^6)

(9/3) x 10^(12-6)

3 x 10^6

We divided the stuff out front like normal (9/3 turns into 3) and we subtract the exponents when dividing the 10^12 over 10^6. The general rule is that

(a^b)/(a^c) = a^(b-c)

The result 3 x 10^6 is in scientific notation. It represents the number 3,000,000 aka 3 million. While 9 x 10^12 represents 9,000,000,000,000 which is the number 9 trillion.
