➷  Multiply 4.6 by 4 to get the sum of the numbers after 5 was added:

4.6 x 4 = 18.4

^ This is the new total

Subtract 5 from this:

18.4 - 5 = 13.4

Divide this value by 3 to get the original mean:

13.4/3 = 67/15

One thumbtack weighs 0.25 ounce. How many thumbtacks are in a box that has a mass of 3500 grams? (Hint: 1oz ~28g
Marina86 [1]
Alright so .25 oz is 1/4 of 1oz.  Therefore you take 28 and divide it by 4 and get 7.

Then take 3500 and divide it by 7 which makes 500 thumb tacks.

I think idk though.

How many ways can u write 5 to the power of 8 as a quotient of two exponential terms?
skad [1K]
Hello,

The answer is "4 ways".

Reason:

You can write it these ways:

= 5^12 / 5^4
= 5^9 / 5
= 5^10 / 5^2
<span>= 5^15 / 5^ 7

Therefore you can write it 4 different ways....

If you need anymore help feel free to ask me!

Hope this helps!
