Is 26,341 divisible by 3?
shepuryov [24]

No.  26,341 is not evenly divisible by 3 .

Here's the trick you can use to decide this
just by looking at a big number:

==>               If a number is divisible by 3, then the
                     sum of its digits is divisible by 3.

I've never taken the trouble to figure out why this works,
but it does work.  I didn't make it up.  It's widely known.

So let's look at  26,341 .

The sum of the digits is  (2 + 6 + 3 + 4 + 1)  =  16 .

16  is not divisible by  3 , so  26,341  is not divisible by  3 .

Is that cool or what !

Solve for u. u/2=1 u=?​
Vikki [24]

Answer:

u=2

Step-by-step explanation:

All you would do is multiply both sides by two so that way you can get the variable by itself, once you do that then it would be 1*2 which is 2.
