Answer 1

The expressions that are equivalent are A, D, and E.

Explanation:

Given:

-7z+ ( - 6.5) + 3.5z + 6y - 1.5.

On solving the equation:

`-7z+ ( - 6.5) + 3.5z + 6y - 1.5`

`-7z - 6.5+ 3.5z + 6y - 1.5`

`-7z  + 3.5z + 6y - 1.5-6.5`

`-3.5z+6y-8`

So, on solving the equation we get the expression:

`-3.5z+6y-8`

According to question:

We see that expressions:

A.
`-8+6y+(-3.5z)`

`=-8+6y-3.5z = 3.5z+6y-8`

So, this expression is equivalent.

D.
`6y-8-3.5z`

`=3.5z+6y-8`

So, this expression is also equivalent.

E.
`-3.5z+6y-8`

So, this expression is also equivalent.

Therefore, the expressions that are equivalent are A, D, and E.
