I just took the test. For K12 first attempt here are the answers:

1.Which expression is equivalent to −1.3+(−4.9)+(−2.6) ?

C. −1.3−(4.9+2.6)

2.Which expression is equivalent to −40+(−20)+(−60) ?

D.−20+(−40)+(−60)

3.Select from the drop-down menu to correctly identify the property shown.

0.8+(1.2+(−3))=(0.8+1.2)+(−3)

(Associative property)

4.Select from the drop-down menu to correctly identify the property shown.

−7.1+(−4.8)+(−1.9)=−4.8+(−7.1)+(−1.9)

(Commutative property)

5.Use properties of addition to evaluate the expression.

−92+(−47)+(−8)

Enter your answer in the box.

Answer: -147
