-3
1/2
3
2

Answer 1

-0.13

Explanation:

cause if u add them then u divide them u get the answer

Answer 2

The value of y is 3.

Explanation:

`DF` is a midsegment, by given.

`AD=DB` and
`CF = FB`, by midsegment definition.

Also, if
`DF` is a mid segment, then
`AC \parallel DF`.

`CF=6(y-1)` and
`FB=4y`, by given.

Replacing each of the segments, we have

`CF = FB`

`6(y-1)=4y\\6y-6=4y\\6y-4y=6\\2y=6\\y=3`

Therefore, the value of y is 3.
