Question 6263: hi...pls help me with this question...it looks really tricky if you cant i dnt blame you because know one know's how to do it!! this is really hard to explain. there is a pic of matches which make a box...the first box is made up of 6 matches the second box is made up of 10 matches but has a line down the middle and the third box is made up of 14 matches and has 2 lines down the middle. then the questions say: write in words 2 rules that tell you how many matches are needed for each number of letters....then the other question says: write both rules in C in symbols uising m for the number of matches and n for the number of letters. sorry i havent explained that very well :(

Question 6389: Find an equation of the line that goes through the point (1,1) and have a slope equal to 1, graph it.
Would my two sets of points be (1,1) and (2,2) since this would be a slope of 1? Not sure how to graph.
Please HELP! This is going to be my last question for some time. I would again appreciate an immediate response if possible. Thank you to whomever answers. You don't know how much I appreciate all the help I have gotten on this site. You are all angels to me. Thanks again.

Question 6879: It has been over 24 years since I have used algebra. I have 2 days until I take a test for an electrition apperentiship. I have to take a simple algebra test. One of the questions is
A=B+3(4-C)
B=5 and C=2
What is the value of A
I know the anwser is 11 (according to the back of the book anwsers)
My question is, how do they get that anwser? I remember that you do the work in the () first which would be (4-2)which would equal 2
so A=B+3(2)
A=5+3(2)
A=8(2)
A=10
Which is not what they say it is.
Could you please tell me where I went wrong in my solving this question and some basic "this is what you do first" type of help.
Thank you,
Ron
