Answer 1

To rewrite the expression, break down each place value and simplify.

Step-by-step explanation:

To rewrite the expression, we need to break up each of the place values.

70 + _____ + _____ + (-30) + (-9) + (_____)

The expression can be broken down as follows:

70 + (0) + (0) + (-30) + (-9) + (0)

Simplifying, we get: 70 - 30 - 9

Therefore, the correct answer is a) 60 - 30 - 9.
