2.6x+2> -12.5

Question

I need help with this i have no idea what I'm doing.??

Answer 1

Hi Amy--

 

It wants to know what value of x will make the sentence true. It's exactly like doing an equation, except that instead of finding out what x equals, you need to find out what x is "greater than" to make it work.

 

Start off as if it's an equation. Step 1, subtract 2 from both sides, so you get:

 

2.6x > - 14.5

 

Now divide both sides by 2.6 to solve for x:

 

x >  - 14.5/2.6,  or x > -5.576

 

It means that you can plug in any value of x that is greater than - 5.576, and the sentence will be true.

 

Hope this helps!
