First....6÷1/2= 12
so.....12*3.9=46.8 milligram
D = 5x - 3y <=ANSWER
<span>8x + 4y - (3x + 7y) = 5x - 3y </span>
<span>13x + y - (8x + 4y) = 5x - 3y </span>
<span>18x - 2y - (13x + y) = 5x - 3y </span>
The answer would be 7/3. You would divide them both by 3. You just divide them by the same number to the point were you cant divide both by the same number anymore. For example 18/9 you can divide it by 2 to get 2.
No, because 14 cups of lemonade divided by 2 is 7, or, $7. $7 multiplied by 3 ( 3 afternoons) is 21, or, $21.
