Take a number. double the number. subtract 6 from the result and divide the answer by 2. The quotient will be 20. what is the number?

Sagot :

23 . the double is 46 - 6 .. divided by 2 ~ 20 
let 'x' be the number
-doubling the number you will have
   2x
-subtracting 6 from 2x and dividing the difference by 2 you'll have:
  [tex] \frac{2x - 6}{2} = 20[/tex]
-cross multiply 2
  2x - 6 = 20(2)
   2x - 6 = 40
   2x = 40 + 6
   2x = 46
     x = 23
therefore the number is 23
