Question

I NEED YOUR HELP BAD!! PLEASE HELP!!!

I have 3 questions that i need answers fast!

Which equations show the associative property?

Select each correct answer.

3.81+(−4.81+(−6.15))=(3.81+(−4.81))+(−6.15)3.81+(−4.81+(−6.15))=(3.81+(−4.81))+(−6.15)

(−7.5+(−1.2))+(−3.7)=−(7.5+1.2)+(−3.7)(−7.5+(−1.2))+(−3.7)=−(7.5+1.2)+(−3.7)

(−1.5+(−8.6))+(−1.4)=−1.5+(−8.6+(−1.4))(−1.5+(−8.6))+(−1.4)=−1.5+(−8.6+(−1.4))

(−4.8+(−0.65))+1.4=−(4.8+0.65)+1.4

Answer 3

hii

Answer 4

Do you know what the associative property is?

Answer 5

its were u can add no matter how the numbers are and the parenthises

Answer 6

Are you missing an equal sign in the first option?

Answer 7

i copyed it from my school

Answer 8

The associative tells you that when you add numbers together, the way you group the numbers together does not alter the result.

This is the typical way the associative property is stated:

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

That shows you that if you group the \(a\) and \(b\) together and add them, and then you add \(c\), you will get the same result as if you group together \(b\) and \(c\) and add them together, and then add \(a\) to it.

Answer 9

i really need help. i know this is hard

Answer 10

Sorry, the equal sign is not red, but it is big.

Answer 11

ok

Answer 12

Look at the first choice now corrected with the equal sign that was missing.

Answer 13

ok now what do i do :)

Answer 14

is it a and c? :)

Answer 15

I'm writing each piece between equal signs in a single line to make it easier to read.
The entire thing below is option A of your answers. I also numbered the lines.

3.81+(−4.81+(−6.15)) Line 1

= (3.81+(−4.81))+(−6.15) Line 2

= 3.81+(−4.81+(−6.15)) Line 3

= (3.81+(−4.81))+(−6.15) Line 4

Answer 16

by the way thank u for all ur help u are amazing

Answer 17

its defenitly A now we have to figure out the others

Answer 18

Aren't math questions confusing?

Answer 19

yes

Answer 20

Look at Line 1.
-4.81 and -6.15 are in parentheses to be added together
Then afterwards, you'd add 3.81 to the sum.

Now look at Line 2.
Now 3.81 and -4.81 are in parentheses grouped together.
You'd add those first, then add -6.15

A change in grouping in an addition is what the associative property allows you to do.
Option A clearly shows the associative property from Line 1 to Line 2.

Answer 21

Good job @mathstudent55 you are really good at math

Answer 22

Now let's look at the other options to see if any other also shows the associative property being used.

Answer 23

Can I tag you when I need help on math questions? lol

Answer 24

@Eiwoh Thanks

Answer 25

ok so A is right now lets look at the other options

Answer 26

In option B, a negative sign was factored out.
That is the same as factoring -1 one.
That is the use of the distributive property, not associative.

Answer 27

yea i didnt think b was right

Answer 28

i dont think D is right but i could be wrong

Answer 29

Here is option C.

\((−1.5+(−8.6))+(−1.4)=−1.5+(−8.6+(−1.4))\)

Look at the left side:

-1.5 and -8.6 are added in parentheses.
Add them first.
Then add -1.4

Now look at the right side:

-8.6 and -1.4 are in parentheses.
Add them first.
then add -1.5 to that.

Does this remind you of the associative property?

Answer 30

You are correct about D.
D is the distributive property just like B was.

Answer 31

What about C?

Answer 32

yes it is..... i think..

Answer 33

@Eiwoh
Yes, you can certainly tag me.

Answer 34

Correct.
C is again change of grouping just like A was.
Answer: A and C.

Answer 35

Good job @DrummerGirl7

Answer 36

yayyyy!! hey can u help me with 2 more i promise it wont take long and i really need u
