Question

This is an off topic question but i feel the need to let other peoples brains keep running so these are the questions i will give you..........
1.)Which expression is equivalent to −4.6+(−0.4)+(−7.2) ?

(4.6+0.4)+(−7.2)
(4.6+0.4+7.2)
−4.6−(0.4+7.2)
−(4.6−0.4)+(−7.2)

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

−40−(20−60)
−(40−20)+(−60)
−20+(−40)+(−60)
40+20+60

3.) correctly identify the property shown here
−1.4+(−2.6+3.8)=(−1.4+(−2.6))+3.8

4.)correctly identify the property shown here
(−6.8+(−5.1))+6.2=(−5.1+(−6.8))+6.2

5.) Use properties of addition to evaluate the expression.

(−64)+((−36)+20)

this is worth 40 pts i will also give brainliest to the one that answers these correctly

Answer 1

−4.6−(0.4+7.2)
−20+(−40)+(−60)

4 and 5 is properties of addition

-80 is your answer

hope this helps

Answer 2

Tha other person who ansered dosent know that
