Which expressions are equivalent to −1.3 (−4.9) (−2.6)−1.3 (−4.9) (−2.6) ? select each correct answer. −1.3−(4.9 2.6)−1.3−(4.9 2.6) −(1.3 4.9 2.6)−(1.3 4.9 2.6) −1.3 (4.9 2.6)−1.3 (4.9 2.6) −(1.3−4.9) (−2.6)

I think the correct answer from the choices listed above is the third option. The expression that is equivalent to −1.3 (−4.9) (−2.6) would be −1.3 (4.9 2.6). Hope this answers the question. Have a nice day. Feel free to ask more questions. Thank you.

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
