I think the charge is 2 but I can't get the coordination number right!  I think it's 6 but I'm not sure.  I only get one try. :(

its 6. The two chlorides are not bonded to the nickel, thats why they are outside the bracket. And yes the charge is 2 to balance the -2 charge of the chlorides.

I would call the credit card company and ask them what the transaction was for. Just tell them that you don't remember what it was for and that you want to make sure that you made that charge to your credit card. Good Luck.

Mutiply $28 by 0.30, then subrtact 28 again, and that should tell you how much it is. ($19.60. It will come up as -19.60 though, just ignore the negative)

rfamilymember is right and so is his method for getting the answer. It's $113.33\n\nJust multiply this by 0.075 to check. (That's 7.5 hundredths, in other words,7.5 per cent.)

I understand your confusion, and suggest that you focus on how the two problems are grouped.\n\nIn mathematics, it's customary to group added terms together using parentheses.  Therefore, the first sum is merely 6.\n\nOn to the next problem:  With nine 1's being added, the sum is 9.\n\nNever would you string these together to form a two-digit answer.\n\n\nHowever, as the first Answerer suggests, perhaps your problem was a single multiplication problem.  In that case (and assuming the problem was written all on one line), you would work it out as he/she did:\n\n (6)(9) = 6 * 9 = 54\n\nHope this helps!

Here's some complicated instructions:\n\nhttp://www.jimloy.com/math/combo.htm\n\nSeems it would just be easier to buy a new one.  They're not that expensive, if your time is worth money

I figured it out... the answer is 1/(13*(2-3x))\nIf you need an explanation tell me

I've never heard that they're not supposed to charge.  I'm sure they've never heard that either!\n\nBut regardless, the reason would be that if you have a skill that others do not, you should use it for the greater good.\n\nThese days, the only place you'll find that kind of altruism is here at Yahoo Answers!

You have to bear in mind that the drinks were not actually $27 dollars, it was $25.  Just because you gave them a dollar each back, they ASSUMED it was $27.\nEven though they had paid $27, you still had to pay their bill of $25 which would leave you the $2.....\nthe missing $1, is therefore, not a missing dollar....!

start with the O... they are always -2\nsince there are 2, and the compound must balance...\nPb must be +4\n\nso you get +4 -2

well there is usually a phone number next to the charge.. call it and ask... otherwise, if no phone number is provided call your credit card company and give them the reference number for that charge and they will be able to provide you with who charged that $16 and a phone number for you to call and clarify who authorized that charge and what for

The uncharged gets charged.

Nothing is lost. Their contribution is 47$ (23.5 $ each). This sum includes the 2$ for the cab, so the 2$ should not be added again to get the 49 sum.\n\n25$   25$\n---------\n1.5   1.5.......back\n1     1.........cab\n22.5  22.5......pen cost\n---------\n25$   25$\n\n=>Each paid 23.5$, the shop received 45 (22.5 from each), and the cab received 2$(1 from each).

HOLY SH*T..........it works......i did it three times.......i dont know how they did it......\n\nand i came up with a different number and i different symbol every time...
