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

Option (c)

Step-by-step explanation:

Let downward direction is negative and unward direction is positive. So, the given condition is :

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.

It means that,

Movements = (-15) m + (4) m +(-7) m

If she uses commutative property :

(-15) m + (4) m +(-7) m = 4 + (–15) + (–7)

Hence, the correct option is (c).

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.
