Which expression is equivalent to −10+(−40)+(−90) ?

D.−10+(−90)+(−40)

S. −10−(40−90)

B. −(10−40)+(−90)

C. 10+40+90

Respuesta :

It is easy, answer D.

If you see, on answer D commutative property is applied.

-10 - 40 - 90 = -140

-10 - 90 - 40 = -140

It is always -140

It can't be S because -10 - (40-90) = -10 - (-50) = -10 + 50 = 40

It can't be B because -(10-40) - 90 = - (-30) - 90 = + 30 - 90 = - 60

It can't be C because it would give +140

So, answer D is right.

Answer:

The answer is D. -10 + (-90) + (-40)

Step-by-step explanation:

It's very obvious and fun to complete.

So we are going to do commutative property which is about changing

operations  but the product stays the same.

And in both expressions, i got the answers -140.

And all those other answers i tested were very very very very wrong.

SO IT'S D
