Answer:

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

Step-by-step explanation:

Given:

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

On solving the equation:

[tex]-7z+ ( - 6.5) + 3.5z + 6y - 1.5[/tex]

[tex]-7z - 6.5+ 3.5z + 6y - 1.5[/tex]

[tex]-7z  + 3.5z + 6y - 1.5-6.5[/tex]

[tex]-3.5z+6y-8[/tex]

So, on solving the equation we get the expression:

[tex]-3.5z+6y-8[/tex]

According to question:

We see that expressions:

A. [tex]-8+6y+(-3.5z)[/tex]

   [tex]=-8+6y-3.5z = 3.5z+6y-8[/tex]

So, this expression is equivalent.

D. [tex]6y-8-3.5z[/tex]

   [tex]=3.5z+6y-8[/tex]

So, this expression is also equivalent.

E. [tex]-3.5z+6y-8[/tex]

So, this expression is also equivalent.  

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