Answer 1

What model can you use to represent −30÷−6?(1 point)
Responses

(−5)+(−5)+(−5)+(−5)+(−5)+(−5)=6(−5)=−30



30−6−6−6−6−6=30−5(6)


−30−(−6)−(−6)−(−6)−(−6)−(−6)=−30−5(−6)=0


(−6)+(−6)+(−6)+(−6)+(−6)=5(−6)=−30

Answer 2

The model represents negative 6 times 7, which is solved by multiplying 6 times 7 and changing the sign to get negative 42.
