I'm assuming that you want to know what we get when we multiply 15 by 3.
15 \times 3 = 45.

If you are confused, then read on. :)

The \times symbol means you add 15 exactly 3 times. 15+15+15=45.

Let's take 3 \times 2 for example. 3 \times 2 is when you add 3 for a total of 2 times. 3 + 3 = 6. You can also say that 3 \times 2 is when you add 2 for a total of 3 times. 2 + 2 + 2 = 6.

So 15 \times 3 = 45.
15 + 15 + 15 = 45
and
3 + 3 + 3 + 3 + 3 + 3 + 3  + 3 + 3 + 3 + 3 + 3 + 3 +3 +3 = 45.

So the answer is 45. :)

A printing company charges $5.00 for the first 400 pages printed. For each page printed over 400, the customer is charged an add
Vadim26 [7]

Answer:

D

Step-by-step explanation:

Up to 400 pages, the cost is fixed at 5.00 dollars

After 400 pages the cost is 0.01 cents/page

  • It's not A. 400 is the number of pages. It is not a cost.
  • It's not B either. B means that no matter how many pages you print, it's going to cost 5 dollars + the number of pages times 1 cent.
  • C is not the answer. It is really just an answer put it. You pay 1 cent for each page between 400 and what you printed.
  • I think D is the answer, but if you get a negative number, then the cost is 5 dollars

3) If you can buy one package of shallots for<br> $4, then how many can you buy with $12?
Olin [163]

Answer:

3.

Step-by-step explanation:

4$ = 1 pack

(think: what times 4 is 12? 3! so we need to muliply both sides of the equal sign by 3, so we can turn the 4 into a 12. Remember, what you do to on side, you must do to the other. )

4$ = 1 pack

*3  *3

12$ = 3 packs

so your answer is 3.

4/6 x what equals 8/6​
Sidana [21]

Answer: 4/6

1. Subtract 8/6 by 4/6.

  • 8/6 - 4/6 = 4/6

4/6 + 4/6 = 8 is the same as:

  • 4 + 4 = 8

<em>Notice: You don't change the denominator if your adding or subtracting.</em>

<em>That's why 4 + 4 = 8 is the same as 4/6 + 4/6.</em>

<em />

<h2>Final answer: 4/6. </h2>
