If the number is represented by variable x, then twice the number is represented by 2x.
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
lets presume the number is X: 2(x+x)+2
x+2x=303x=30 x=10
x=-3 or x=5
Twice the number n is 2n.
The GCF of x and 2x is x.
If you have a number x, then twice that number is 2*x and so the expression means 42 - 2*x
One less than twice a number = (X times 2) minus 1, (where X = your number of choice).
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.
If the number is represented by variable x, then twice the number is represented by 2x.
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
lets presume the number is X: 2(x+x)+2
Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7
Twice 50 (2 x 50) = 100
x+2x=303x=30 x=10
