Answer:
1. 5 + (-2), 5 - 2, and 3
2. 7 + 2
Step-by-step explanation:
1. If we look at the model, there are 5 positive circles and 2 negative circles. This means that we can write it in :-
- 5 + (-2)
- 5 - 2
- 3 --> *5 - 2 = 3*
2. It asked for an equivalent to 7 - (-2). Remember that negative and negative would be positive. So, it would become 7 + 2.
I would appreciate if you give me the brainlist or not. Hope this helps and stay safe, happy, and healthy, thank you :) !!
