Since x^-2 = 1/x², 1/x^-2 = x²

Now, since 1/x^-2 = x²,

---> 1/3^-2 = 3² = 9

---> 1/3^-4 = 3⁴ = 81

---> 1/1^-2 = 1² = 1

A cube root is a number that, when used in a multiplication problem 3 times, gives the answer.

Since 4 x 4 x 4 = 64, 4 is the cube root of 64.

Incorrect.

9=2=-1=-5=n

It does not matter what the number is because the equation is incorrect.

NOTE:

W+W+3W=95

5W=95

W = 19

Will gets 19, Debbie gets 19 and Dave gets 57

Debbie E Dave A Will W

Will has some sweets.

Dave has 3 times as many as Will whilst A=3W (1)

Debbie has 3 less than Dave. E = A/3 so A=3E (2)

So Will and Debbie have the same number of sweets. 3 times less than Dave. W=E

W+W+3W=95

Will : Dave : Debbie

W : 3W : W Divide by W

1 : 3 : 1

You are on an online calculator website, you don't need to ask "what does 500 divided by 9 equals" because you can easily type it into the calculator and it will give you the answer

Hi Gibsonj

Vince received a credit card statement that has a new balance of $676.76 and a minimum payment of $49.78. The annual percent rate is 15% compounded daily and charged on the unpaid balance. Vince makes only the minimum payment. He makes no other purchases. How much interest will Vince be charged on the next statement in 15 days? Show your work."

$676.76 - $49.78 =$626.98

$626.98 x (1 + .15/365)^15=$630.86

$630.86 - $626.98 =$3.88 Interest charged in 15 days.

Tips: Break the worded question down to a way that you can actually understand. Figure out what you're actually trying to find. If you find most worded questions difficult look up ways to help with them or ask a teacher for some advice/help/extra work.

Oh gosh, this is actually surprisingly hard. Have you tried writing it out so you can visually see it? or just trialed and errored. I'm close but I haven't quite gotten it yet. My closest was Dave=14 Will=45 Debbie=35 Then I realised Debbies didn't work! Maybe you can mix around with the numbers I just gave you a bit? Good luck!

Dont worry, I'm trying to figure it out right now. Just wait a few minutes and I'll give you the answer in long form so you can atleast simplify it. :)
