The additive inverse of 2/8 _________​

Answer 1

Step-by-step explanation:

5x + 2x = 7x

Additive inverse of 2/8 = 8/2 = 4

Answer 2

Answer:

sorry brother I tried in another way this is also same formula.

Step-by-step explanation:

Correct option is

A

3x+5

3−2x

The additive inverse of a number is what you add to a number so that the sum will be zero. In other words, the additive inverse of x is another integer y, as long as the sum of x+y=0. For example, the additive inverse of 5 is −5 because their sum 5+(−5)=0.

Similarly, the additive inverse of the fraction

3x+5

2x−3

is −(

3x+5

2x−3

) or

3x+5

3−2x

and their sum is determined as:

3x+5

2x−3

+(

3x+5

−3+2x

)=

3x+5

2x−3−3+2x

=

3x+5

0

=0

Hence, the additive inverse of

3x+5

2x−3

is

3x+5

3−2x
