I've honestly did this so many times and the answer I'm getting is not even there! :( a - 2b / c If a = -8, b = 6.5, and c = -2. 10.5 -9 -1.5

OpenStudy (precal):

a-2b/c -8-2(6.5)/-2 -8-13/-2 -8+6.5 -1.5 use order of operation

OpenStudy (lukecrayonz):

Sorry he got it right D:

OpenStudy (anonymous):

Great. Two different answer!

OpenStudy (anonymous):

Are you sure?

OpenStudy (precal):

I am correct. Lukecrayonz forgot that 2 is -2

OpenStudy (anonymous):

Thank you both! :)

OpenStudy (lukecrayonz):

No, I forgot the division part goes before subtraction while on top.
