Well... You had the right idea but the wrong setup
30 = x + (x + 3) + (x + 6) + (x + 9) + (x + 2) 30 = 5x + 30 30 - 30 = 5x 0 = 5x 0/5 = x 0 = x Which means zero acres were burned in the first hour, then 3 acres the second hour, and so on.
hmm a little ambiguous
@dan815, -15/6 acres could not have been burned in the 0th hour.
yeah i know its werid but.. having 0 burnt in 1 hour with a fire is messed up too
i kinda just assumed -15/6 was some constant to make the equation work where time must be greater than 1 u know
0 acres are burned, but maybe a few feet or some miles are burned.
then itb be point something lol
dont forget those rationals
theyre still part of the real numbers
The equation was setup in terms of acres. And if there was meant to be an exact integer solution, then no, it wouldn't be point something.
yep but they have integer solution only in the question man
i agree that the solution is for this case given the level of difficulty is probably x=0 for time 1 but just saying it was a little ambiguous
they have to say* integer solution only in the question
do you understand now?
I understand that my solution is correct and yours isn't. You don't have x = 0 you have x = -15/6 which doesn't make any sense.
no u see you have a solution that works, mine is another solution dont get angry lol
there are an infinite solutions that work, due to the ambiguity in this question
they just needed to state some restrictions
try to be a little more flexible with your reasoning it will help you later when you learn more math
The thing is, you assumed a 0th hour. So the 0th hour would have to mean something in context with the given question. But in the context, -15/6 doesn't mean anything in context with the question.
why do you say that?
this is math -15/6 could mean something
you see since they didnt say integer solutions only
lets say that for your case, where fire is at 0 given time = 1
would 30 mins of time not exist?
or any other time inbetween 0 and 1 hour, but in that case you will have a negative solution too
you see what i am trying to get you to understand?
no but you have 0 acers in 1 hour, so how 1.5 acers at the 0.30 time mark
I mean, some miles
again with that
In the first hour zero acres are burned. The equation is defined in terms of acres not anything else.
remember rationals again
you can have fractions of an acre
Of course, but this problem is set up for convenience.
let's assume, in your case that -15/6 for zeroth hour means nothing. Then how many acres was burned in one minute?
some negative ammount
it just doesnt make sense for us
Exactly, which definitely makes no sense
but if i were to say there is a restriction on time where this equation is valid which i did then it does
hold on ill try to find some good videos for you, you seem interested in this stuff
I didn't ask for any videos.
You can feel free to look at them on your own.
im just pulling your leg:)
I suppose the question is ambiguous since no restriction was defined. I just the real question is, what is the default assumption for a question like this? Would it be one where the result would make sense, or one where the result makes no sense?
there we go
my solution actually would make sense too, id have all positive values for hour 1 to 5
but it wouldnt definitely be the wrong solution given what the teacher is really looking for
you see mathematically speaking
the solution y=3x-15/6 would even make more sense than y = 3x because it has positive values sooner
ok im sorry!! ill stop messing with you
I'm already aware of the mathematics
You haven't shown me anything I don't already know.
i know that i mean ill stop teasing you
Teasing is something immature kids do.
iam very immature :)
anyway! hows your programming
I recently decided to start learning some python
I hate programming
could use some help with coding!
coding is fun!! you get to try all that stuff you learn in math out
It's only useful if you plan to eventually create something beneficial for humanity.
Something you've already thought of
Fortunately, they've already built calculators.
i just want to get good at coding so i can do more of those annoying time consuming stuff i do with the computer faster
also not that literally everyones got an iphone or something like that.. we can make sure of our programs anywhere we go!!
