hi do u know the answer to the questions i need them by tomorrow morning at 5 thanks
can u start out by answering the first then i can do it on my own and finish the rest
my name is shree
Pleasure to meet you ^.^
do u get the question, i am stumped
let me see... i will write as i read :)
k thanks for helping
planetarium program cost: 5 per yr n=visits per year perks for being a member: 2 dollars of ticket (non-memeber pirce: 13 dollars)
ok i got this information from number thirteen
k did u get the answer
working it out xD
sorry take ur time
N = llx + 13y hmm im a little confused by the question but this is what i got :)
X being the amount members visiting, and why the non members
that's what i got too but solving it was the hardest part i tried to search everywhere
to solve for it we would need to make up an x and a y
i think that x=13 and y=11 but how do you justify that that is your answer you know by using mathematical steps
it says that they have to be equal thats why
where does it say it has to be equal?
it says it on number 13
ohhhhhhhhhhhhhhhhhhhh i see, i just skimmed it XD
let me re make the equation then :)
11n = 13n
do you get it?
yeah but when it says n is the number of total visitors, it just gets confusing
ok let me explain it :)
n is the number of visitors, in other word total visitors not just members or vice versa. with me so far?
then how do you know how much n is
one sec let me finish explaining that then we will get to that :)
hmm let me make an analogy (a fictional example to help relate)
so if i were to try and get people to join a program i would try and show them the benefits, or how much money they can save correct?
i just confused my self... let me step back andre think this from the beggining
ok.. after some quick thinking ive come up with a new equation
5 + 11n = 13n
wow it makes sense now :D
yeah because of the +5 of the yearly thing but how about justifying it
with this equation we get 2.5 visits per year which is wrong.. but we are on the right tracks now!
lets make one more change to the equation
remebered i said N was the total visits correct
this means that n can not be the same for both 11 and and 13
yeah beacuse not the same amount of people have membership and not so ur right
so the new equation is 5 +11x = N - 13y
i just dont get how you will get n or x or y
hmm same... but lets ee
it would be easier if we knew what n was wouldn't we
hmm i just had an idea, let me try working it out on my side...
i am sorry to hurry you but i need to go and could u type the answer i will check in the morning sorry i an stay for 10 minutes
Alright ill see if this idea leads to the answer :D
thns u have soooooooo much help
what grade r u in
whaa... i am in 8th
but i finished highschool math last year xD
im taking college lvl math now ^.^
omg i have been waiting for colledge like forever
i cant wait to go
to think i passed calculus to be struggling on a middle school math problem u.u
college is fun :d
and hahaha well common core algebra 1
do u come home from colledge or stay there
oh guess that's why u r even here
I GOT ITTTTTTT
After many errors it all clicked!!!
we where right the first time! well... errr third time or whatever it was
the correct equation is 11n +5 = 13n
what we need to prove is that buying membership and paing 11 dolars or just not being a member is the same in this equation
so following the equation if you only go 2.5 times a year then it will cost you the same as if you buy membership and go 2.5 times a year
11(2.5) = 27.5 =27.5 + 5 =32.5 13(2.5) = 32.5
we did it!
i was mislead by the impossibility of visiting 2.5 times, but that doesn't matter, the question is just asking for an equation that would make it theoretically possible for them them to result in the same price!!
as for a property of equality...
we used the subtraction property of equaltiy
5+ 11n (-11n) = 13n (-11n)
subtraction equality means that if we subtract the same number to both sides we still end up with the same equations for example the equation 5=5, if we subtract the same numbeer from both sides, it will still be true. 2-5 =5-2 = 3=3
number 15 i think i answered by saying that you would have to visit 2.5 times etc....
wow that was hard! That is the most thinking ive done in a while hahaha,
thnx sooo much
u were really helpful i guess that finishing calculus really paid off huh
i finally got it and no u got the answer with the very little help i was able to give thank u sooo much that was easier than i thought wow |dw:1441805152704:dw|
Np! It was fun :P
and nice art skills :D
And calculus is never worth it xD
i even reccomend taking statistics over precalc
