2x ???
To write twice the sum of a number and 600, you first express the number as a variable, such as ( x ). The sum of the number and 600 can be written as ( x + 600 ). Therefore, twice this sum is represented as ( 2(x + 600) ).
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
To express a number decreased by twice another number, you can use algebraic notation. Let’s say the first number is represented by ( x ) and the second number by ( y ). The expression would be written as ( x - 2y ), indicating that you take ( x ) and subtract twice the value of ( y ).
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).
To write twice the sum of a number and 600, you first express the number as a variable, such as ( x ). The sum of the number and 600 can be written as ( x + 600 ). Therefore, twice this sum is represented as ( 2(x + 600) ).
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
