thanks can I ask another?

The statement above says "Simplify this problem"

3 , 36/12 so it would be x/12

What do I do to figure this out? I divided 24 by $27.60

Just looked up the word illogical lol.. It would be D but how?

606.00 1018.00-606.00= 412.00 but how did you get 84,372 and 44???

you would divide 24 by 27.60 right?

Jack what does that mean?? Thanks REINY for your help

Wait it is D right?

It couldn't be D because that more than 27 jars 27.60/24=1.15 24/27.60= 0.86956521739(rounded 0.87) Which one would it be?

That's what I did: 27.60/24 right? That's 1.15

Can you also check my student survey plz?

-0.8b + 3.2=2.4 (b) 4.1c - 0.1=4 (c)

What does 10.8 (b) what does (b) mean and (c)

And look at Reiny's post: We can only add "like" terms, so the b's go together and the c's go together -0.8b + 4.1c -(-3.2b) - 0.1c = -0.8b + 4.1c + 3.2b - 0.1c = 3.2b -.8b + 4.1c - .1c = 2.4b + 4c

Can you check my HELP PLZ post and my student survey plz?
