Mateo begins his dive at sea level. He dives down 15 meters, and then rises up 4 meters. He dives again, going down 7 meters. Which equation models Mateo’s movements, and uses the commutative property?
(–15) + 4 + (–7) = (–7) + (–15) + (–4)
(–15) + 4 + (–7) = 7 + 15 + (–4)
(–15) + 4 + (–7) = 4 + (–15) + (–7)
(–15) + 4 + (–7) = 4 + 15 + 7

Answer:
(–15) + 4 + (–7) = 4 + (–15) + (–7)
Step-by-step explanation:
We are given that he dives down 15 meters, so this will be -15. Then, he rises up 4 meters, so this is 4. Then, he goes back down 7 meters, or -7. So, we have (-15) + 4 + (-7). The commutative property states that we order the number in any way we want, and the only choice that works is (-15) + 4 + (-7) = 4 + (-15) + (-7).
