The product of a certain number and 5 is equal to twice the number subtracted from 20 find the number
2/6 /7
Let's find the solution step-by-step.
Let's assume the number is represented by the variable "x".
According to the given information, the product of this number and 5 is equal to twice the number subtracted from 20.
So, we can write the equation as:
5x = 20 - 2x
To find the value of "x", we need to simplify and solve the equation:
5x + 2x = 20
Combining like terms, we have:
7x = 20
To solve for "x", divide both sides of the equation by 7:
x = 20/7
Simplifying the result, we get:
x = 2.857
Therefore, the number is approximately 2.857.
To find the number, let's represent it with a variable. Let's call the number 'x'.
According to the given information, "the product of a certain number and 5 is equal to twice the number subtracted from 20."
We can translate this into an equation as follows:
5x = 20 - 2x
Now, we can solve this equation to find the value of 'x'.
Let's simplify the equation:
5x + 2x = 20
Combining like terms, we get:
7x = 20
Now, divide both sides of the equation by 7 to isolate 'x':
7x/7 = 20/7
Simplifying the expression, we get:
x = 20/7
Therefore, the value of the number is 20/7.
x = number
The product of a certain number and 5 is equal to twice the number subtracted from 20 means:
x ∙ 5 = 20 - 2 x
5 x = 20 - 2 x
Add 2x to both sides
7 x = 20
x = 20 / 7
