you r asking a number whose twice will be 4 but less than 8. so, take a no. x. by ques. 2x=4; 2x=4; x=4/2; hence x=2; 2 is answer and less than 8 of twice it.
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
sum - means addition less - means subtraction twice - means multiply by 2
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 ).
20
15
2n - 2
um, 9.
if a number is "x" then it is 2x-16
2x - 2
