hm. okay i guess. How about this one: 150 people went to see "Ode to Algebra" performed in the school auditorium. If the number of children that attend the performance was, c, how many adults attend?
you tell.. 150 people went to see it children were C.. so how many left?
i don't know, thats why I'm asking I'm a bit confused. Can you please explain?
total people 150.. out of them 'c' number of them were kids.. so how many left??
I'm sorry I'm lost. Its confusing me, wouldn't it be 150=a+c ?? I'm sorry I don't really understand.
lets start simple if i said.. out of 10 people 4 were children.. how many are adults?
so that was 10 - 4 similarly out of 150.. c number of them are children.. hence the answer would be???
OH. 150?
:O c is a variable.. c could be 1 or 2 or 150... so the answer is 150 - c
I feel stupid. But WHY would it be 1 , 2 , or 150?
thats algebra.. its a variable.. a variable could be any number!!! so in general.. it would be 150 - c
Oh. okay. But since its saying to find the amt of adults, then wouldn't it be 150-c=a ?
ok ok. yes.. 'a' is a variable that you are assigning to adults :)..
Ohh ok! Thank you so much!
no probs ;-)
hey can you help me again??
