Best ResponseYou've already chosen the best response.0to graph a line you need a minimum of 2 points the easiest to use what is x when y = 0 and what is y then x = 0 to find the solution as stated above find where the lines cross

Best ResponseYou've already chosen the best response.0At the end of May, Janet told Sam that she has read 10 books this year and reads 2 books each month. Sam wants to catch up to Janet. He tracks his book reading with a table on his door. Using his table below, what month will Sam have read the same amount of books as Janet? Month Books June 3 July 6 August 9 November December January March i got november?

Best ResponseYou've already chosen the best response.0This is throwing me off `Janet told Sam that she has read 10 books this year and reads 2 books each month` if she read 2 books each month, then she actually has read 2*12 = 24 books total for the year. How can they say she only read 10 books in a year?

Best ResponseYou've already chosen the best response.1I had a different approach.. that's why I was hesitant to answer it said at the end of May she told Same that she read 10 books this year and reads 2 books each month so it's at the beginning of the year... from January to May .. since the whole year hasn't be completed yet

Best ResponseYou've already chosen the best response.1I'm thinking that since it's at the end of May and we now know that it's 10 book and reads 2 a month January 2 Febuary 2 and so on until May

Best ResponseYou've already chosen the best response.1omg lack of sleep. It's probably starting at January and then at the end of May it was revealed that she read 10 books so far this year... She reads 2 a month so she was reading 2 books for 5 months.. January, Feb, March, April May

Best ResponseYou've already chosen the best response.1and he's like ok I'm going to catch up.... let me just start at June but instead of 2 a month, it's 3 a month

Best ResponseYou've already chosen the best response.1so he's like first month 3 books.. makes sense first month x 3 books 1 x 3 = 3

Best ResponseYou've already chosen the best response.1second month x 3 books 2 x 3 third month x 3 books 3 x 3 and then I'm assuming that he takes a break and restarts in November now fourth month x 3

Best ResponseYou've already chosen the best response.1So Sam's Chart was Month Books June 3 July 6 August 9 then we have November, so he didn't read for September and October that could be Sept 0 Oct 0 November (resumes reading) or something like that and I see the multiples of 3 being used too before his break

Best ResponseYou've already chosen the best response.0@triciaal you're on the right path it should be 2x + 10 = 3x though x = number of months since May eg: x = 0 represents may x = 1 represents june x = 2 represents july etc

Best ResponseYou've already chosen the best response.0oh wait the equation isn't 2x + 10 = 3x solve for x to get 2x + 10 = 3x 2x + 102x = 3x2x 10 = x x = 10 may is the 5th month 10 months from there is 5+10 = 15 the 15th month is really the 3rd month since 1512 = 3

Best ResponseYou've already chosen the best response.0@UsukiDoll I had it wrong because I did 12 months not from May 5 2 = 3 the 3rd month March

Best ResponseYou've already chosen the best response.1@triciaal I figured out my mistake . Apparently Sam's Chart blended into the Multiple choices so I assumed that Sam took breaks when in fact he didn't so he did started in June by reading 3 books a month until Sam can catch up with her. So Sam was the multiple of 3 and she was the multiple of 2. With enough reading, both of them will catch up with each other in March for reading 30 books.

Best ResponseYou've already chosen the best response.1Janet was a multiple of 2 and started reading in January.. so by March she will have 30 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 (1 year and 3 months_ Sam was a multiple of 3 and started in June 0 0 0 0 0 3 6 9 12 15 18 21 24 27 30 (1 year and 3 months) Although he had a late start, adding one more book in his reading list proves to be successful later on.
