20% of a number is x what is 100% of the number assume x is greater then 0

                           x is 20% of Number

                           x = (0.2) x (number) .

Divide each side by  0.2 :     Number =  x / 0.2 

                                             Number = 5x .

'x' can be anything, even zero.  This equation works for x=any number.
  

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
