If two angles form a linear pair such that the measures are represented by 4x-20 and 5x-40, what is the value of x?

OpenStudy (anonymous):

They will add up to 180, so to solve for x 4x-20+5x-40=180

OpenStudy (anonymous):

I got 12 but the answer choices are (1) 20 (2) 80/3 (3) 40 (4) 40/3

OpenStudy (anonymous):

9x=240 x=240/9 simplify that fraction and it matches one of your answers

OpenStudy (anonymous):

80/3?

OpenStudy (anonymous):

Yes
