Question

PLEASE HELP WITH NUMBER PROPERTIES!? I WILL MEDAL AND FAN

Answer 1

i think you combined a few steps in the first steps

Answer 2

I simplified, but I have no idea what to put in the other column

Answer 3

i recommend you start over.

and let your first step to be distributiving 3(x-y)

Answer 4

3x-3y

Answer 5

Okay, so the first part would be 3x-3y (distributive property) ??

Answer 6

yes. but you would want to write the whole thing. not just that part on the left side

3x+4y +3x -3y -4x

Answer 7

what would you do next

Answer 8

Next, 3x+3x-4x + 4y-4x (Rewrite the equation?

Answer 9

yes. and close^. the last term should be -3y

and what would would you use?
associative, commutative or distribute?

Answer 10

remember
distributive: ex.2(x+y)= 2x+2y
assocaitive: ex. 2+x+4= 2+(x+4) *you're putting parathesis to show you want to solve these together first
commutative: ex. 2+x+4= 2+4+x *you're rearranging the terms(usually grouping w/ other similar terms)

Answer 11

or commutative

Answer 12

commutative since all you did was rearrange the terms

Answer 13

Okay, So next 2x+y (Solve it??

Answer 14

@nikato

Answer 15

no. you skipped a step

3x+3x-4x+4y -3y

(3x+3x-4x)+(4y -3y)
group like terms.
and what propoerty would this be?

Answer 16

associative Property?

Answer 17

correct.

and your next step would by 2x+y

and reason could just be simplify

Answer 18

Alright, Give me a min to show you my work, so you can check it. :)

Answer 19

ok

Answer 20

Answer 23

Alright Awesome.

Answer 24

@nikato

Answer 25

What do you think?

Answer 26

no.
you could've checked your answer.

6x45=270
but your answer choice equals 54

Answer 27

find an answer choice where the equation equals 270

Answer 28

So C?

Answer 29

6*45=270
6*40+6*5 =270

Answer 30

@nikato

Answer 31

yes
