Answer to Problem 30PPS

Variable: x; 2x  >  x+9 ; The number is greater than 9.

Explanation of Solution

Given:

Twice a number is more than the sum of that number and 9

Concept Used:

Let the variable be ‘ x’

Now convert the condition given in the question into an inequality.

Twice a number is more than the sum of that number and 9

Twice a number = 2x ; more than means the sign is >

The sum of that number and 9 = x+9

Twice a number is more than the sum of that number and 9: 2x  >  x+9

Calculation:

Inequality: 2x  >  x+9

Solve for x :

  2x  >  x+92x−x>x−x+9   [ Subtract  x  from  both  sides ]x>9  Check  the  solution  when  x  =  122x  >  x+92  ·  12  >  12+924  >  21  [ True  statement ]

Solution: x>9 or (  9  ,  ∞  )

Thus, the required number x is greater than 9 .
