For each of the following, find all possible whole-number replacements that make the following statements true.
123 = 7 • 17 + ______
7 * 17 = 119
119 + what? = 123
well 123 - 119 = 4
so try 4
Does 123 = 119 + 4 ?
Yes, so 4 is the answer.
To find the whole-number replacements that make the statement true, we need to determine the missing number in the equation "123 = 7 • 17 + ______."
We can start by simplifying the right side of the equation:
7 • 17 = 119.
So the equation becomes:
123 = 119 + ______.
Now we can subtract 119 from both sides to isolate the missing number:
123 - 119 = ______.
This simplifies to:
4 = ______.
Therefore, the only possible whole-number replacement that makes the statement true is 4.
