how much has tery?
1 and 2/3 as many cookies as jennifer
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.
but you have to have get j by yourself
check your answer 32 + 32(1.667) is not equal to 480
oh. i did that completely wrong
32 + 32(1.667) is not equal to 480 equals 85.333 cookies
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?
1 over 5/3. 1 / (5/3) which is 3/5
I'm so confused
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?
I'm still confused
I'm sorry :(
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?
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 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?
do you multiply the 5/3 to 480
is it 320 for teri
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.
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
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.
mathmale technically they only asked for the number of cookies Jennifer has.
I still don't understand what I'm supposed to do if i can't do the reciprocal
but it is good to solve for both and add them together to check your answers
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.
