Answer:A
Step-by-step explanation:all u have to do is try out every option and see if the answer equals to 0.
We will see that the thing that we can replace in the given equation that makes it true is the one in option A.
A) -6.7 +6.8
We have the equation:
-4.5 + 4.4 + ? = 0
And we want to see how we can complete it such that it is true. Remember that an equation is true if and only if the thing at the left is equal to the thing at the right.
Then we can just solve the equation for "?"
-4.5 + 4.4 + ? = 0
-0.1 + ? = 0
? = 0.1
So from the given options, we need to see which ones are equal to 0.1
Then the only thing that could replace the "?" is the one in option A:
? = ( -6.7 +6.8 )
