Answer:

$8.75

Step-by-step explanation:

Let x = the amount the man originally had

The man has $x and says "if you give me $x, I will spend $10."

y = amount he has after 1st proposition = x + x - 10 = 2x - 10

He repeats this procedure, now with $2x-10 in his pocket...

z = amount he has after 2nd proposition = (2x - 10) + (2x - 10) - 10 = 4x - 30

He repeats this procedure, now with $4x-30 in his pocket...but this time he is left with zero dollars...

r = amount he has after 3rd proposition = (4x-30) + (4x-30) - 10 = 8x-70 = 0

8x - 70 = 0,

x = $8.75

(X^3)^1/3 <br> What is the simplest form of this expression?
Norma-Jean [14]

3 * (1/3) = 1
So it would be x^1 or just x

What is the check digit, d, for the UPC bar code number shown below? 0-24679-36163-d
Juli2301 [7.4K]

Answer:

The check digit is 7.

Step-by-step explanation:

Check digit can be calculated by the following way:

  • Add all the digits except the check digit that is the last digit on the   right side.

             Total = 0 + 2 + 4 + 6 + 7 + 9 + 3 + 6 + 1 + 6 + 3

             Total = 47

  •      Add the digits at odd starting from left, double this amount and          finally add it with the total from step 1.

             = 0 + 4 + 7 + 3 + 1 + 3

       Sum =  18

      Doubling the sum = 36

     Adding it with the total from step 1, we get

        Total = 36 + 47

        Total = 83

  •  Subtract the last digit of the total from step 2 with 10, and this will be check digit.

        Check Digit  = 10 - 3

        Check Digit  = 7
