Question

This looks really hard, I am pretty sure I can solve what they want but it would take me a while and I need some guidance...
-3(x - 5) - 8(y + 2) + (-3)(6 - 4b)

All I know is that it wants to find the end number of non variables. Like the first one is -3 x -5. since its -3( x - 5)...

The only thing that confuses me is the random (-3)(6 - 4b) Like what?

Thanks if you help ;)

Answer 1

Help please??????

Answer 2

what is the goal here? to eliminate the parentheses?

Answer 3

No its to find the total sum of the non-variable number. Like A. -3x - 8y -15
B. -3x - 8y +15 C. -3x -8y + 20 D. -3x -8y -20

Answer 4

So your trying to find the "End" number

Answer 5

is the "total sum of the non-variable number" of \(-3x-8y-15\) equal \(-15\)

Answer 6

-3(x - 5) - 8(y + 2) + (-3)(6 - 4b)
Answer it from here.

Answer 7

the only way i can make sense out of this is to "remove the parentheses using the distributive property, then combine like terms?

Answer 8

for example \[-3(x-5)=-3x+15\]

Answer 9

Yeah Like that, but were not trying to find the -3x ***TAKE THAT ALL OUT*** and keep the 15, then go on to the next distributive and get the non-variable then add it to the +15

Answer 10

And keep Going till theres no more of the problem

Answer 11

ok

Answer 12

so we ignore the \(-3x\) and hold on to the \(+15\)

Answer 13

Yes.

Answer 14

then what do you get when you disitribute the \(-8\) in the term \[ - 8(y + 2) \]?

Answer 15

A. -3x - 8y -15

B. -3x - 8y +15

C. -3x -8y + 20

D. -3x -8y -20

Are the answers.

Answer 16

those answers all have \(x\) and \(y\) in them!

Answer 17

See how the end has different numbers? Focus on THAT not the x's and the y's cause their all the same, You getting me?

Answer 18

no

Answer 19

..........

Answer 20

distribute \(-3(x - 5) - 8(y + 2) \) and see what you get

Answer 21

you will defiinitetly get \(-3x\) and \(-8y\) for sure

Answer 22

All the answers on my thing say Minus 8 not negative 8

Answer 23

15 + -18 RIght???

Answer 24

ok i can see why you are confused

Answer 25

if the the question is \[-3(x - 5) - 8(y + 2) + (-3)(6 - 4b) \] then the answer will have to have a \(b\) in it

Answer 26

can you post a screen shot?

Answer 27

I got D... Cause 15 + -16 = -1 which then -18 + -1 = -19??

Answer 28

ughhh

Answer 29

what did you do with the b in the expression?
why does it disappear?

Answer 30

is b suppose to be a type-o?

Answer 31

Ughhh This is so stressful but here...
I forgot to put 12b...

Answer 32

Im sayin D

Answer 33

oh the problem makes way more sense now

Answer 34

yes
15-16-18=-19
the answer D above is not correct
but the answer D on the page you showed here is correct
