Write your answer...

twice the difference of three times a number and eight

One number is eight more than twice another if their difference is 25. The larger number is 42

2n-4

negative 5

Infinity

the number is negative two.

Twice a number minus two giving us the answer as eight is number 5.

Eight added to twice a number is 42.Give the number the name of ' X '.8 + 2X = 42' X ' is 17.

2x/8; x = the number

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.

The difference between a number x and twice y is equal to fifteen.

It's an example of converting something easy into something nearly impossible, and then expressing it obscurely. Behind the veil lies an almost trivial algebra exercise. Although the question doesn't ask for the solution to the exercise, here it is anyway, at no extra cost: -- The difference between (eight times a number) and (twice the number) is (six times the number). -- (Six times the number) is eighteen. -- (the number) is one-sixth of eighteen, or three.

Twice a number increased by eight is greater than negative four.

It does not mean anything at all. "Twice a number" is only one number while "the difference" must refer to two numbers, not just one.

Twice the number is something like 3x2, 4x2.... Squared is 3x3, 4x4. It's one number multiplied by itself twice

2x + 8

If the number is x then the expression is: 2x+8
