Which of the following expressions is equivalent to (1/9 • 9) • x -9?

Answer 1

To simplify the given expression, we can perform the operations inside the parentheses first:

(1/9 • 9) • x - 9

First, we can simplify 1/9 • 9:

(1/9) • 9 • x - 9

9/9 • x - 9

Since 9/9 simplifies to 1, we have:

1 • x - 9

Now, we can simplify 1 • x:

x - 9

Therefore, the expression is equivalent to x - 9.
