Explain why 2-81273-05213-8 is an invalid UPC number.
sammy [17]

Answer:

Part 1) Is not a valid code

Part 2) The last digit should be 6 in order to make it a valid code

Step-by-step explanation:

we have

2-81273-05213-8

we know that

The last number is the check digit (8)

<em>Verify the UPC number</em>

step 1

Sum the digits in the odd positions, starting at the left

so

2+1+7+0+2+3=15

step 2

Multiply the answer in step 1 by 3

15(3)=45

step 3

Sum the numbers in the even positions, ignoring the last (12th) digit because that is the check digit that you are verifying

Do not multiply this number by 3.

8+2+3+5+1=19

step 4

Add the results from steps 2 and 3

45+19=64

step 5

Subtract the number in step 4 from the next higher multiple of 10. In this example, the next multiple of 10 after 64 is 70, so subtract 64 from 70:

70-64=6

This number is not equal to the check digit (8)

therefore

Is not a valid code

The last digit should be 6 in order to make it a valid code

cricket20 [7]

Answer:

Eliza is 1

Step-by-step explanation:

If Eliza is 2 years younger than 1/2 her brothers age and Juan is 6.

  • - divide 6 by 2 (6÷2=3)
  • - Take 3 away from 2 ( 3-2=1)

So that means Eliza would be 1
