what is the answer to the an umknown number
To find the unknown number, we can start by setting up an inequality based on the given information.
Let's assume the unknown number is represented by 'x'.
According to the question, the unknown number decreased by 9 is at most 27. This can be expressed as:
x - 9 ≤ 27
To solve for 'x', we need to isolate it on one side of the inequality. We can do this by adding 9 to both sides of the inequality:
x - 9 + 9 ≤ 27 + 9
Simplifying the equation:
x ≤ 36
So, the unknown number, 'x', is less than or equal to 36.
