Simplify \[2x - (3 \times 0.6x + 2.7\]

OpenStudy (anonymous):

@sammixboo

sammixboo (sammixboo):

Does the parenthesis end at the end of the expression?

OpenStudy (anonymous):

I like Sonic Kirby @pooja195 :)

OpenStudy (anonymous):

Oh yeah

OpenStudy (anonymous):

yeah it does, sorry.

OpenStudy (anonymous):

LOL 23 of my smart score is engagement.

sammixboo (sammixboo):

Ok! Well, we have \(\color{blue}{2x -(3\times0.6x+27)}\), right? Since there is nothing it's equaling to, we are going to simplify this

OpenStudy (anonymous):

Whoa whoa wait.

OpenStudy (anonymous):

This is a multiple choice question.

OpenStudy (anonymous):

Sorry.

OpenStudy (anonymous):

Here are the choices.

sammixboo (sammixboo):

To start simplifying this, multiply 8 by 0.6x to get what?

sammixboo (sammixboo):

3 not 8, jeex typos

OpenStudy (anonymous):

\[A. -2.5\] \[B. 2.5x\] \[C. 0.2x + 2.7\] \[D. 0.2x - 2.7\]

OpenStudy (anonymous):

There we go!

OpenStudy (anonymous):

Those are the choices!

sammixboo (sammixboo):

Okie dokie. We have \(\color{purple}{2x-(3\times0.6x+27)}\) Can you tell me what is 3*0.6x is?

OpenStudy (anonymous):

Well first off, we don't know what \[x\] is.

OpenStudy (anonymous):

For all of you lazy people who want an answer to the question, it's letter D.

OpenStudy (anonymous):

Which is, 0.2x - 2.7, which I found out, thanks to @sammixboo
