Determine which of these illustrates two quantities that combine to make 0.

Answer 1

To determine which of these illustrates two quantities that combine to make 0, we need to look for pairs of numbers that add up to 0.

1. 5 + (-5) = 0: This pair of numbers combines to make 0.
2. -2 + (-7) = -9: This pair of numbers does not combine to make 0.
3. 4 + 4 = 8: This pair of numbers does not combine to make 0.
4. -12 + 12 = 0: This pair of numbers combines to make 0.
5. 1 + (-8) = -7: This pair of numbers does not combine to make 0.

So, option 1: 5 + (-5) = 0 illustrates two quantities that combine to make 0.
