September 6, 200520 yr Yeah, this is pretty lame, but whatever... We were assigned this problem over the weekend, and I'm completely stuck. 0_o a __ x d = c a+12 Solve for a? (or get 'a' by itself) That's a over a + 12... if it's not clear...
September 6, 200520 yr :o I got an "E" in maths, last year..... I don't even know what an E is...... I'm sorry, I can't help! :cry: :stunned: Math scares me. LMFAO!
September 6, 200520 yr Wow, is it really that bad? It's only Algebra... :P I havent done algebra in over 10 years!! :cry: :embarrased:
September 6, 200520 yr Haha sorry. I only remember these things when we were given what D and C was. I forget what type of algebra this is... 3 was a guess. 3 _____=5 and I dont know what c is, so I dont know how to work out d. 3+12
September 6, 200520 yr Author 0_o "Get 'a' by itself". Yeahhh... that sounds simpler than "solve for 'a'"
September 6, 200520 yr Ahh! Haha, always read the question. 'Solve' and 'Equate' are such different things. It must be 3.
September 6, 200520 yr Author a = c/d xa +12 ?! nah, it can't be. 'a' can't be on both sides if you're solving it. :(
September 6, 200520 yr a = c/d xa +12 ?! Thats right! Now I remember these shindigs... Basically its just reversing the equation.
September 6, 200520 yr d a _____ * d = c a+12 fist--divide c on both sides a _____ = c/d a+12 second---- you cross multiply a (d) = c (a+12) third----you multiply c(a+12) a(d) = a© + 12c fourth-----you minus a© from both sides a(d) - a© = 12c fifth-----you take out a common factor of a from " a(d) - a©" a(d-c) = 12c sixth-----divide both sides by (d-c) a = 12c/(d-c) HOPE WAS CLEAR ENOUGH
September 6, 200520 yr i took calculus in 11th grade and calculus 2 in 12th-------for me that equation is like asking 1 + 1 = ___ I love math
September 6, 200520 yr Re: d a _____ * d = c a+12 fist--divide c on both sides a _____ = c/d a+12 second---- you cross multiply a (d) = c (a+12) third----you multiply c(a+12) a(d) = a© + 12c fourth-----you minus a© from both sides a(d) - a© = 12c fifth-----you take out a common factor of a from " a(d) - a©" a(d-c) = 12c sixth-----divide both sides by (d-c) a = 12c/(d-c) HOPE WAS CLEAR ENOUGH What use can that possibly be in everyday life?? :huh:
