Let the unknown number be x and so the algebraic expression is: 2x -13
twice a number can be 2x and six less than it is 2x-6.
The number is 55. 55 - 13 = 42.
Given a number N, you would have: 2*N - 5
Let the number be x and so the expression is: 2x-2

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.
twice a number can be 2x and six less than it is 2x-6.
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.
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
One less than twice a number = (X times 2) minus 1, (where X = your number of choice).
