Write down what we know first.. Jennifer has J cookies Terry has j times 1.667 cookies (or 3/3 + 2/3 = 5/3) together they have J + J(5/3) = 480 cookies Solve for J. Show me.

480/5/3?

=32

No
anonymous
  • anonymous
but you have to have get j by yourself
retirEEd
  • retirEEd
check your answer 32 + 32(1.667) is not equal to 480
anonymous
  • anonymous
oh. i did that completely wrong
retirEEd
  • retirEEd
32 + 32(1.667) is not equal to 480 equals 85.333 cookies
retirEEd
  • retirEEd
Yes you did do it completely wrong, but you were right in that you need to get the J by itself. Show me

do you do the reciprocal of the 5/3?
retirEEd
  • retirEEd
1 over 5/3. 1 / (5/3) which is 3/5

I'm so confused
retirEEd
  • retirEEd
It's an invert kind of thing, like the reciprocal of 2 is 1/2.

I'd let j=number of cookies belonging to Jenn, and t=number belonging to Teri. Then t = 1.67 j, or t= (5/3) J, or t = (1 2/3)*j. What would the sum of t and j equal, and why?
anonymous
  • anonymous
I'm still confused
anonymous
  • anonymous
I'm sorry :(
retirEEd
  • retirEEd
j + t = 480 J + J (5/3) = 480 Solve for j. How can you isolate the J ? It is confusing at the beginning just hang in there.

do 3/5 on both sides?
mathmale

J=# of coookies Jenn has t=(5/3)j=# of cookies Teri has 480=total number of cookies the girls have If you add t and j together, what does that sum represent? Can you eliminate one of the variables, either t or j?
retirEEd
  • retirEEd
What?
mathmale
  • mathmale
RetirEEd wrote the following: j + t = 480 J + J (5/3) = 480 Solve for j. How can you isolate the J ? this is precisely what I was recommending. See if you can find the value of j. Once you have j, find t.

you take the reciprocal of the 5/3 correct?
retirEEd
  • retirEEd
No
anonymous
  • anonymous
do you multiply the 5/3 to 480
anonymous
  • anonymous
is it 320 for teri
retirEEd
  • retirEEd
No. What you do to one side of the equation you have to do to the other side. if you multiply 5/3 to 480 you have to multiply it to the J + J (5/3). And that won't isolate the J.
retirEEd
  • retirEEd
Show me the work first, isolate the J. And tell you if it is right.

If you want me to get the js by themselves don't I have to do the reciprocal? Cause thats the only way i know how to get the J by itself
mathmale
  • mathmale
j = # cookies Jennifer owns t= # cookies teri owns = (5/3)j j+t=j + (5/3)j =480 cookies, total. Solve for j. then find t.
retirEEd
  • retirEEd
mathmale technically they only asked for the number of cookies Jennifer has.
anonymous
  • anonymous
I still don't understand what I'm supposed to do if i can't do the reciprocal
retirEEd
  • retirEEd
but it is good to solve for both and add them together to check your answers
retirEEd
  • retirEEd
Last clue....... The left hand equation has a J in both terms. Factor out the Js and divide both sides by the what is left in the parenthesis. Have a good night. Time to watch my Cowboys loose.
