In a stick of chalk carbon is 3 g what is the weight of the chalk stick

Step-by-step explanation:

let chalk contains 10x calcium, 3x carbon, 12x oxygen.

percentage of carbon in the chalk:

=                  3x              x 100

        10x + 3x + 12x

=  3x    ( 100 )

   25x

= 3 (4)

= 12%

Now, we know that carbon has 12% of chalk.

weight of carbon = 12% x weight of chalk. equation

plugin values into the equation:

3 = 12% (weight of chalk)

3 =   12     (weight of chalk)

      100

  12     (weight of chalk) = 3

 100

weight of chalk = 3 (100)

                               12

weight of chalk = 25g

answer: haha (: i’ll go see what it is

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
