The answer is $2.50. 

The cost of each bag of popcorn is $2.50

The answer is the second option 2.50 because if we multiply 2.50 or 2.5 by 12 to get the amount of 12 popcorns then it gives us 30 which when subtracted from 40 leaves 10 , so your answer is 2.50 !

Hope uve understood by now but if not then pls be free to ask!

The answer is 16.7 cm^2.

Thanks DragonSlayer!

Yes. I agree with rosala because the associative property basically repeats the same thing, but it kind of switches around.

mari379, I'm going to tell you how to find the answer:

Mutiply the base times the height and divide that answer by 2.

Remember that your answer will be _________ cm² 

sorry once again for posting twice by mistake!wont repeat it(ill try my best)!

oh okay!i was just wondering!

x*x*x*X*X=x⁵

The easiest way to solve this is to count how many x's are there and then but the 5 as the power.

x=base 

5=power

This is an example of Associative Property of Addition ( the second option) because in this property the rule is 

a+(b+c)=(a+b)+c

So this

2 + (x + y) = (2 + x) + y 

is matching to the property!Thats is why the answer is the second option!

not really. i just need help

Umm!i just wanted to ask you one thing Mari , are these home work questions we are all answering!

What is the symmetric property? I never heard of that property.

My educated guess is 10 kilometers per second.

Then whatever they r i just cant see them , the main bits which are showing the amount or numbers!

Thanks CPhill for the chance of answering this!

as CPhill said , according to his examples i am going to tell you its answer Mari!

$$x*x*x*x*x=x^5$$ $$ANSWER$$ 

(as ther are 5 x's we are multiplying so we'll take the power of x as 5)

Hope this helps!

their is no pictures?

2+4=6 You can use the calculator too.

Go ahead, rosala

Mari i cant see the pics!pls can u do something about this because or else i wouldnt be able to help you!

Thanks, rosala

CPhill can i answer this please!

No. Thanks, Melody. I will try googling it.

So we'd solve this like;

$$2x-8y+3x^2+7y-12x$$  ( now we will place the like terms together)

$$=2x-12x-8y+7y+3x^2$$  (now we'll simply solve them)

$$=-10x-y-3x^2$$  (now we'll place them in a proper order)

$$=3x^2-10x-y$$  $$ANSWER$$

So your ANSWER IS THE second option!

Hope this helps!

I'll give you a hint here:

x * x =  x²

x * x * x = x³  

That should help
