Step-by-step explanation:

Set A is a subset of set B if all the elements of A are also the elements of Set B.. (common element)

The above set have 0 common elements so.. if there is no common element and are subsets then it means that there arent any elements in both the sets

so, the answer for the question would be "both the Sets A and B are the empty sets"

C. The first is a solution, but the second is not.

5x - y/3 = 13 ; (2,-9)
substitute the letters:
5(2) - (-9/3) = 13
10 - (-3) = 13 : note that deducting a number with a negative sign turns both sign as positive.
10 + 3 = 13 ;
13 = 13

5x - y/3 = 13 ; (3,-6)
5(3) - (-6/3) = 13
15 - (-2) = 13
15 + 2 = 13
17 = 13 not equal. not a solution

hope i could help

when you are dividing two decimals how can you check whether you have divided the decimals correctly?

Mice21 [21]

Dividing two decimals means that we need to make the following math operation:

$\frac{p}{q} \\ \\ where \ p \ and \ q \ are \ two \ decimals$

According to the following definition:

$If \ p \ and \ d \ are \ two \ real \ numbers \ (two \ decimals) \ it \ is \ true \ that:\\ \\ p=d\times q+r \\ \\ where:\\ \\ p:Dividend \\ d:Divisor \\q:Quotient \\ r:Reminder$

We can prove that our result is correct by multiplying the divisor by the quotient plus the reminder and verifying that this result matches the dividend. Also, we can use a calculator to prove that.

Printer A can print 30 pages per minute. Printer B can print 40 pages per minute. Printer B begins printing 3 minutes after Prin

anzhelika [568]

Printer A prints for 10 minutes, so prints

... (30 pages/minute)×(10 minutes) = 300 pages

Printer B prints for 7 minutes, so prints

... (40 pages/minute)×(7 minutes) = 280 pages

At the end of 10 minutes, the two printers will have printed

... 300 pages + 280 pages = 580 pages
