Sorry the "Total Items $$ Total" was supposed to be 3 columns.
Okay, I have figured this out. Total Items $$ Total Books 175-v 5 5(175-v) Videos v 6 6v Total 175 --- $910 5(175-v) + 6v = 910 875- 5v + 6v = 910 1v (or just v) = 910-875 v = 35, or 35 videos 35 videos at $6 each = $200 sold $910-200 = $710 left for books
Pls help me. Pls tell me some bases (alkelis)other than any cleaning products.
I haven't learned what cot and csc are. Can I still solve this with just tan, cos, and sin?
but if I have identical denominators, why can't I just add the 1 to the tan^2X?
I'm really sorry. I don't want to sound stupid, but when I add tan^2x/tan^2x to 1/tan^2x I get 1+tan^2x/tan^2x and then the tans cancel out and I'm left with just one. Obviously, that's not correct, but I can't find my mistake.
okay, I'll try it out, thank you.
wait, for the first one if sin^2+cos^2=1, how did you even cancel some out?
oh, ok, I see. thank you all very much. I think I get it now, so hopefully I can actually get them on my own. :)
