6 times the difference of a number and 9 is 18 less than the number.
I need to write out as an equasion. Help!
6(n - 9) = n - 18
Six times the difference between x and 11 is at most 18.
Let's break down the problem into equations step-by-step:
Let's suppose the unknown number is "x".
The difference between the number and 9 is "x - 9".
According to the problem, 6 times the difference of a number and 9 is 18 less than the number. In equation form, this can be written as:
6(x - 9) = x - 18
Therefore, the equation is 6(x - 9) = x - 18.
To write this as an equation, let's break it down step by step:
1. "A number": Let's represent the unknown number with the variable "x."
2. "The difference of a number and 9": The difference between the number (x) and 9 can be expressed as "(x - 9)."
3. "6 times the difference of a number and 9": Multiplying the difference by 6 gives us "6(x - 9)," which represents "6 times the difference of a number and 9."
4. "Is 18 less than the number": We can express this as "18 less than x" by subtracting 18 from x, which gives us "(x - 18)."
Putting it all together, the equation becomes:
6(x - 9) = x - 18
This equation represents "6 times the difference of a number and 9 is 18 less than the number."
