Q: What is twice X in Pre-Algebra?

Write your answer...

Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)

2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y

Generally, "twice" means double. So, twice X is equal to X plus X. Twice four is eight. simmisinghsaini's answer- But however, doesn't it mean to divide when we have to translate algebraic expressions?

pethagoreum theory a2+b2=c2

I divided it by 2 twice, then by 3 twice, then by 5. 2 x 2 x 3 x 3 x 5 = 180

Let x be the number you are looking for. Since -14 is twice x we write -14 equals twice x or in symbols.-14=2xx=-14/7 or -2So the answer is -2

x+4.

8 is twice as big as 4. 9 x 8 is twice as big as 9 x 4.

If you have a number x, then twice that number is 2*x and so the expression means 42 - 2*x

If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8

Let's call "a number" x. Then 5 more than twice x is 5 + 2x.

2 (x + y)

Twice 50 (2 x 50) = 100

x*2

2x ???

Twice divided by the cube of the sum of x and 2 is equal to 2 times the reciprocal of ((x + 2) cubed)).

The GCF of x and 2x is x.

One less than twice a number = (X times 2) minus 1, (where X = your number of choice).

2(3 + x + x2)

x multiplied by 2
