twice of a number added to half of itself equals 20. find the number.
2N + .5N=20
X=8
Let's represent the number as 'x'.
The equation can be written as:
2x + (1/2)x = 20
To simplify, we can multiply the entire equation by 2 to eliminate the fraction:
4x + x = 40
Combining like terms, we have:
5x = 40
To isolate x, we divide both sides of the equation by 5:
x = 40/5
Simplifying, we find:
x = 8
Therefore, the number is 8.
To find the number, we can set up an equation based on the given information.
Let's assume that the number is represented by the variable "x."
The first piece of information we have is that "twice the number added to half of itself equals 20."
In mathematical terms, this can be written as:
2x + (1/2)x = 20
To solve this equation, we need to simplify and isolate the variable "x" on one side of the equation.
Multiplying each term by 2 to eliminate the fraction gives us:
4x + x = 40
Combining like terms, we get:
5x = 40
Finally, to isolate "x," we divide both sides of the equation by 5:
x = 40/5
Simplifying further, we find:
x = 8
Therefore, the number is 8.
