Sarah used properties of operations to simplify the expression. Identify the property she used at each step. 1) -1.85+2.3+(-0.45
)=2.31+(1.85)+(-0.45)
2) =2.3+[(-1.85) + (-0.45)]
3) 2.3 + (-2.3)
4) = 0
1 answer:
We have the following expression:
-1.85 + 2.3 + (- 0.45)
Step 1:
Commutative property of the addition:
2.3 + (-1.85) + (- 0.45)
Step 2:
Associative property of the addition:
2.3 + [(-1.85) + (- 0.45)]
Step 3:
