so hint: can you write 4 equations to represent this paragraph?
umm i got some but i dont know if they are correct, lets say the number = abc a=1/4b b=? c=1/4(a+b) a+b+c = 17
ok lets only use 1 variable can you alter your equations to show me that?
the equations are good though
i dont know what u mean by altering the equations to 1 variable sorry
(I just appreciate you trying) so instead of having a, b, c maybe only have b in one big eq
oh okay! 1/4b + 1/4([1/4b]+b) + b = 17 like that?
exactly can you solve for b now?
i cant seem to figure it out :/
ok let's do it together
so I am going to start by distributing the 1/4 in the second term. can you write this step for me?
do u mean 1/4b + 1/4([1/4b]+b)? sorry im a big confused
ok give me a min and ill explain better
okay thankyou so much
http://www.educreations.com/lesson/view/for-oly-surf/7121943/?ref=link this should explain it
did that help?
thankyou yes it did, but when i figured out 25/16b=17, i got b=10.88 is that right?
sorry i just saw the end of the video, what do u mean by plug it in for a and c?
probably I didnt calculate it and by plug it in a mean just (1/4)b=a(first digit) so thats (1/4)(10.88)= bla bla bla
i dont think its right, like my calculations, sorry i just cant get the 3 digit number dont worry if im being complicated i can ask my teacher
ok h/o I'll redo the problem because you're right it doesn't make sense
okay thankyou so much appreciate it
ok I redid it and got the same answer are you sure you copied the problem correctly?
what 3 digit number did u get?
You can't get one, thats the problem lol
yeah haha thought so! one sec il check if i wrote it correctly
if you only took the first digit it would be 213..
but it dosent equal 17 thats the problem
The first digit of a three digit number is one quarter of the second digit. The third digit is one quarter the value of the number formed by the first two digits. The sum of the three digits is 17. What is the number? This was definitely the question
ok well... I think they messed up lol let me try another approach
dont worry if u cant find it thanks for the help anyway
sorry I couldn't get it... I mean that is the answer. I guarantee it but that is so odd
no worries thanks anyway
@Hoa , can you double check this for me please?
@nincompoop can you double check this for me?
xyz x/4=y z=x+y x+y+z = 17 sorry but I didn't use any mathematical methodologies to answer this… I came up with 287
not x+y it is 1/4 of xy The third digit is one quarter the value of the number formed by the first two digits. we are not using algebraic operations
1/4 of 28 is 7 our first two digits in 287 is 28
OMG! formed as in put together... I'm such a nitwit usually I read formed as add
I thought I was going to embarrass myself in front of you…. I was sweating bullets (lol's)
lol ha it's cool but i would have never thought of just making a number by putting them together. That works... although it's more of a riddle than a math problem in that case
