Answer 1

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:

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

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

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

$-3.5z+6y-8$

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.
