Question

ALL of my students got it wrong !

Crystal normally spends twice as long on the bus to school as tom, but last week the bus was delayed for 10 min. just before tom got on.

Answer 2

Answer 3

Well once they learn there needed skills they all get it.Its still the 1st week of school give em break.

Answer 4

What is it you are testing here?  If mathematical skill then you have clouded the question with unnecessary clutter.

If cognitive skill then it makes me read it several times and I gave up answering as I'd rather use my cognition for some thing more enjoyable ;]

Answer 5

No, this isn't too hard, maybe they just needed a refresher, explain the equation to them, and ask them another word problem very similar using different names and letters, if they don't get that one...then you've got a problem!

Letters always through me off when I was in 7th grade, I never thought letters and numbers should mix, but I did figure it out!

Answer 6

OMG I KNOW THIS ANSWER!!!!!

GRAPES!!!!!!!!!!!!

Answer 7

2x+10=c

x=c.

I always sucked at word problems.  Am I right?  Have patience with those seventh graders.  Word problems are hard for a lot of people.  It isn't the way that you are always taught math.  It is more left brained than right brained.

Answer 8

I got this answer

c = 2f +10
