can someone help me solve this problem?
What is the value of x?
I don't get the last part
where did the 12 come from?
Perhaps I am missing something but I think the 8 + 12 is just another way of writing 20.
If 8x = 160, then
x = 20
and we COULD write it as 8 + 12 although I don't know why we would want to do so.
ooh dur lol me nither but theres a multiple choice answer in my book and i guess that's it. Thank You
