the question i dont get isnt it 50/50 if its a technical sense?

Z and Happy, are you talking about question or egeclaw's comment?

im sorry i.....still dont get it?

Yeah. The point is, we are trying be the result when someone search math questions.

No...it doesn't

yes please explain caus that dosent make sense?

$$\frac{72}{32}=\frac{9}{4}=2\frac{1}{4}$$

Not beeing mean, I just thought you were taking questions from Google.  I mean most people here have probably searched them and know the answers.

$${{\mathtt{5}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{{\mathtt{2}}}^{{\mathtt{4}}}{\mathtt{\,-\,}}{{\mathtt{7}}}^{{\mathtt{2}}} = {\mathtt{351}}$$

Yes, geno. You are right.

Can you explain?

Egeclaw, this question is very well-known.

And I got this from textbook which is Edexcel AS and A Level Modular Mathematics Statistics 1.

What I'm doing here is just wanna share good questions and have fun.

I should have mentioned it, sorry for that.

2 1/4?????

Yeah!

5+20=25

25*2=50

50-15=35

That is assuming x means multipulication!

i dont think it is a vaiable because a number is always in front of a variable or the variable is by itself.

multiple answers whic one is it 2 1/4 , 4 , 7 , 8 1/4

wok in and out of the parenthisis 20+5=25 then 25*2=50-15 then boom 35 see did it without the calculator you know the phrase look mama no hands well look melody no calculator!

You got this question from Google, I serched up "Math Problems" and that came up.  Make your own questions?

Switching from the one that you originally chose to the one not shown by the host gives you the best overall probability of winning.

Is x a multipulication symbol?  Or variable?

Guys, to give you guys hint,

one of two doors is more likely to get sports car.

LOL!!!!!!!!!

I'd say....peek then choose the winner!  That probably isn't an option of that though, is there?

I know you were just kidding.

you cant cause no matter how many curtains you switch too. Your probability of winning is still a split 50/50 because there are only two doors left

The factors of 60 are:  1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Since only 50 books can be on a shelf, the usable factors are:  1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30

Using 6 shelves:  6 x 10 = 60

Using 5 shelves:  5 x 12 = 60

Using 4 shelves:  4 x 15 = 60

Using 3 shelves:  3 x 20  = 60

Using 2 shelves:  2 x 30 = 60
