In the equation x-5=10, what does x equal? What does x equal in the equation 3x=9

Step-by-step explanation:

x - 5 = 10

add 5 to both sides

x -5 = 10

  +5     +5

x = 15

3x = 9

divide both sides by 3

3x = 9

3     3

x = 3

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

8+(1)(8)

8+8

16

retail price is $16.

circle area = pi * 25

circle area = 78.5398163397 square units
