The number is 55. 55 - 13 = 42.
Given a number N, you would have: 2*N - 5
twice a number can be 2x and six less than it is 2x-6.
2n-10
2x-3 , where x is the number referred to in the question
13 < 2n - 5 < 21
Twice the difference between a number and thirteen can be written as 2 (b - 13) Five more than twice the difference between a number and thirteen can be written as 2 (b - 13) + 5. The algebraic expression is 2 (b - 13) + 5.
Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7
If the number is n then twice the number is 2n and 7 less than twice the number is 2n - 7This could also be a boolean variable based on another variable. If the number is less than or equal to 3.5, the variable is false. Otherwise, it is true.
One less than twice a number = (X times 2) minus 1, (where X = your number of choice).
If the number is 'z', then five less than twice the number is ( 2z - 5 ).

if a number is "x" then it is 2x-16
