have to simplify and justify
jimthompson5910 (jim_thompson5910):
b+2+5b ... Start with the given expression
(b+5b)+2 ... Group like terms
6b+2 ... Combine like terms
So b+2+5b simplifies to 6b+2
OpenStudy (anonymous):
how did you get 6b
OpenStudy (anonymous):
you also mixed it up
jimthompson5910 (jim_thompson5910):
b+5b is 6b
5b is basically saying 5 times b
5 times b is the same as b + b + b + b + b

I placed the b term first
jimthompson5910 (jim_thompson5910):
6b+2 is the same as 2+6b
OpenStudy (anonymous):
I understand the b 5 times but how did you get 6
jimthompson5910 (jim_thompson5910):
oh, b = 1b
So b + 5b = 1b + 5b = (1+5)b = 6b

My teacher would count that wrong

what wrong?
OpenStudy (anonymous):
ummmmmmmm this is confusing
jimthompson5910 (jim_thompson5910):
b + 5b is the same as saying one copy of b added to 5 copies of b
So one copy + 5 copies = 6 copies
jimthompson5910 (jim_thompson5910):
put another way, one banana + 5 bananas = 6 bananas
OpenStudy (anonymous):
I understand now
