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?

(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?

did that help?
 one year ago

oly.surf Group TitleBest ResponseYou've already chosen the best response.0
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?
 one year ago

FibonacciChick666 Group TitleBest ResponseYou've already chosen the best response.1
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

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

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

z=1/4(x+y)
 one year ago

nincompoop Group TitleBest ResponseYou've already chosen the best response.1
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

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
