Question

What is the simplest form of the expression (–11.7y – 3.3x) + 1.2x + (5.2y + x)? –16.9y – 5.5x –16.9y – 4.5x –6.5y – 2.1x –6.5y – 1.1x

Answer 1

D

Explanation:

D

Answer 2

(D)
`-6.5y-1.1x`

Explanation:

The given expression is:

`(-11.7y-3.3x)+1.2x+(5.2y+x)`

Upon simplifying the above equation, we get

`-11.7y-3.3x+1.2x+5.2y+x`

Rewriting the above expression by writing the like terms together, we have

`-11.7y+5.2y-3.3x+1.2x+x`

Solving the like terms, we get

`-6.5y-1.1x`

which is the required simplified form of the given expression..

Hence, option (D) is correct.
