Question

When the following expression is written in simplest form, what is the coefficient of the variable term?

-2.5y + 8y - 10.5y

5.5
0
-21
-5

Answer 1

Answer: -5

Explanation:

`-2.5y + 8y - 10.5`

`= 5.5y - 10.5y`

`= -5y`

Hence, the answer is
`-5`.

Answer 2

• D) -5

---------------------------------------------

All terms have same variable of y.

Collect all terms and simplify by adding up the coefficient:

• -2.5y + 8y - 10.5y =
• (- 2.5 + 8 - 10.5)y =
• (-5)y =
• -5y

The coefficient of the variable is -5.
