twice the difference of three times a number and eight
2(x - 7) = 8
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 and so the expression is 4x -3
2 x = 8 + 4x
It is 3*n - 5
This is an algebraic expression. It can be written as 3(2x + 4)
Double mean to multiply.For example: the algebra expression 2x can be written in the English Phrases like-Double a Number-Twice a number-Two of a number-Two times a number-or the product of two and a number.
If the number is represented by variable x, then twice the number is represented by 2x.
The expression "twice the difference of x and 5" would look like this: 2(x-5). To solve the problem, you would first subtract 5 from x, and then multiply the difference by two.
2x-4x = numbertwice = 2 times xless = -and 4 = 4put it all together and you get the answer (2x-4)
It can be: 2x-25 or 25-2x or maybe the absolute value of (2x-25).
2x + 11
Let's call "a number" x. Twice that number would be 2x, and then add 27, so the expression would be 2x + 27.
twice a number means a number times 2
If the number is x then the expression is: 2x+8
2x - 16 = 3x/18
twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.
