Answer:
4
Step-by-step explanation:
UPC (Universal Product Code) is a numeric symbol used in retail products. UPC has two variants, an 11 digit UPC Type A bar code and and 6 digit UPC Type E bar code.
The given UPC code 78007305233 is an 11 digit UPC Type A bar code.
1) From the right to the left, starting with odd position, we need to assign the odd/even position to each digit.
0 E 0 E 0 E 0 E 0 E 0 [0 stands for Odd, E stands for Even]
7 8 0 0 7 3 0 5 2 3 3
2) Summing up all digits in the odd positions and multiplying the result by 3
(7+0+7+0+2+3)*3 = 19 * 3 = 57
3) Summing up all digits in the even positions
8+0+3+5+3 = 19
4) Summing up the results of step three and four
57 + 19 = 76
5) Now, divide the result of the fourth step by 10. The check digit would be the number which adds the remainder to 10. In our case, upon dividing, 76 by 10 we get the remainder 6. The check digit is the result of 10-6 = 4.

Hey there :)
Let

Answer:
x=2 or x=8
Explanation:
Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.
Step 2: Use a factoring strategies to factor the problem.
Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.
Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.
x2+16=10x
Step 1: Subtract 10x from both sides.
x2+16−10x=10x−10x
x2−10x+16=0
Step 2: Factor left side of equation.
(x−2)(x−8)=0
Step 3: Set factors equal to 0.
x−2=0 or x−8=0
x=2 or x=8
