< OR =

lets see

we have

A  B   23  C D

the mean is 20 so that means they add to   5*20 =100

100-23 = 77

So choose any 4 numbers that add up to 77

Next time, just one question per post, thanks  

Your answer is right but your logic is wrong.

10 ways to pick the girl, 10 ways to pick the boy But the girl can be president or vise, once the girls' position is fixed so is the boys so that is 2 ways

answer  10*10*2 = 200

6 vowels

6/26  

It will be x minutes past 9

Big hand  360/60 * x = 6x  degrees  (past 12)

Little hand = -90+x/2 

difference =  6x- (-90+x/2) = 6x+90 - x/2 = 90+ 11x/2

90+11x/2 = 139

11x/2       =  49

11x          =  98

x =8.909090....

x approx = 8 min  55 sec

It is approx  8 minutes and 55 sec past 9

I just checked.

None of your questions have been whited out.

Maybe it was a temporary glitch.

If you click on your username and then on 'my profile' you will get access to all of your posts.

(Maybe not if they have been whited out or hidden but none of yours are whited out or hidden)

Nice answer Ginger 

I'd look at the 4 cases individually   (pos can include zero I guess)

x and y positive

x and y both negative

x pos and y neg

y pos and x neg.
