we are solving for x right?
yes
check your answer: x=-14 x/7 -8 = (-14)/7 -8 =-2-8 =-10
no no you can't do that when x/7 no
why?
whenever you see / it means divide
so therefore we x divided by 7
yeah, i know, when you change sides, it becomes mutiplying
correct
???
but you have to change sides with addition (or subtraction first before you can change sides with division)
so it should be 7x=-14
then divide by 7?
no it's divided here so that can not happen
anytime you have something divided by something you times it
in order for the x or whatever you are solving for.
ok, let's do this one for clarity.......1-n/5=12
subtract -1 from both sides...
you have n/5=11
so the answer is 55?
negative sign!
you should have -n/5 =11
-11?
oh, I see!!!
guys if you are doing this right than have X=??
-55
1- n/5 =12 1 -1 -n/5 =12-1 -n/5 =11 -n=55 n=-55
yipee!
gr8! just make sure you don't get confused with the signs
oh I see what you are doing now, I go step by step that is why I was thrown off by what you did
sry!
6t +3=-7
subtract 3 from both sides
and you can always check your answers by substituting x=? in you equation
6t=-10
divide by 6?
yes
answer is -2?
what is -10 divided by 6?
something isn't right, that is not one of my answwer choices
10 goes into 2 five and 2 goes into 6 3 so the answer is -5/3
well your steps are all correct...
I didn't have the lowest denominator
usually the answers are in simplest form, so simplify your fractions
what choices do you have?
Tiffany I am so sorry about this, I was trying to walk through the steps here so you could ask questions. if you have this I will go
I have -5/3 as an answer
no before you said -2
right, but godorovg came up with -5/3 and I have that as an answer choice
I did not simplify
unless it says to do it I would leave as is
15=-15-8u
add 15 to both sides
30-8u
30=-8u
then what?
divide by -8?
yes
15/-4?
-15/4?
yes
I need help with this one 0=1/6y+8=
subtract 8 from both sides
yes
0-8 is 0?
-8?
yes, -8
-8=1/6y
now what?
can I help here, this problem you are making it harder than it has be
because the variable is in the denominator, therefore we have to switch it to the other side
-8=1/6y -8(6y)=1/6y times 6y
so you multiply both sides with 6y
yes that is right, although when you first start this collect all a like terms and move then to one side and than times through the number being divided
show me
okay let us take this one x/7-8=-10 now here is how I would do this First take the -8 and add 8 to the -10 so now we have this x/7=-10+8 than take this and do the sub to get -2 so now we have x/7=-2 once you have than take the seven ant times to the two so now we have X= -14 like that
ok
-8=1/6y?
okay now you tell me
multiply both sides by 1/6?
you multiply both sides with 6y
yes
but it is 1/6 not just six
so y=1/6x8?
yes
or 48?
it should be y=1/-48
oh yes, because it was a -8
since: 1/6y =-8 1/(6 times-8) =y so, y=1/-48
yes it that is the y=1/-48
okay, thanks guys! I'm tired...going to bed, goodnight! Thanks for your help!
hey no problem glad I could you help you :)
gd nite!
tiffany great job!!
u too!
it's funny that when erinhass says good night , it's actually good morning for me. :)
yeah and it's night time where I am as well
u live in the states?
yes Portland Ore
oh, good for u, i've always wanted to live in the states
yeah funny thing I have always wanted to leave the States
guess we would all like to explore more.
no not to just explore, it falls under the job market here stinks and the education system is messed up for kids, although I don't have any/
i'm a victim under the education system in hong kong :(
yeah i have heard about that as well. I am a math person that you can graphs in my head and will be studying Engineering Physics soon
I am what some would call human calc
:) good for you, sometimes i do that , and miss steps in exams, got a b instead of a, frustrating
yeah, that is why I tell all people that i work step by step in that way you can go back to see what is wrong.
yeah, i know, that's why i have to be extra careful when i'm doing my exams. And i do tutoring, helps a lot with my presentation skills
it drives me nuts sometimes on here when I see people skipping around. that is just plain doesn't make sense to me
sometimes people skip unintentionally, you know, they calculate in their head, and skipped a few steps, sometimes they don't notice it.
yes true and may be this is something I will have to deal with, still I can not understand why skip steps what does that prove?
i personally think if one is confident with that particular question, and skipping a little steps is alright, just don't skip major ones, step on scrap papers, yes you can skip, but steps in exams, no.
i just tell myself be considerate, and help the techer go through the papers as smoothly as possible, work hard for years just to make sure i won't skip anything.
you just made a fan.
u too.:), and thx.
That is what I try to do here, only that I want the person I am helping to tell what they know and I help from that point
I don't just do the work for them..
yeah, sorry about that , will work hard for that, for me it's kind of harder to explain when not face to face
yeah, I can how it could be hard for you, but if you want sometime I can give you tips on to do things a little better only if you want tips
*see
yeah, of course, pls do, i'm all ears :)
okay first what type of math do you help with this mostly?
algebra, calculas, and the basics, just high school stuff.
okay with all these subjects, you need to get the student in which you are helping to tell what they need help with.
than before you do any of the work have them show you what they know about that problem already and ask to see what they are having trouble with
ok
than once the it is clear, work the problem by typing it out in words and than draw it like you were doing. In the typing step by step always so the student can see what is happening where
ok, thx a lot!
sometimes it won't matter if draw the problem if student doesn't get what is going on. So that is why I type it out in all steps
yeah, i find that if students can figure out the problem themselves, it has a greater impression on them
that is always my goal as well.
for example this x/7-8=-10 the student wasn't getting it the whole thing that is why I typed out the steps to show that they are making it too hard.
also to get the student to ask questions as well
yeah, interaction helps.
A must in math, because you and the student have to be involved in order to teach
also just know you won't be there when they are tested. so have the student do the work and you just guide them
unless they just not getting it.
absolutly right, are you like, a teacher?
No. I am a Physics Engineering major in college
cool, always have love physics, physics rocks!
yeah, and bio sucks
same here!
Chem and Physics oh yeah,,
uh huh
Bio not on your life
Anything to do with math I love
sry, mom needs me to have lunch, gotta go.
okay have nice day
cya latter
talk later :)
