DId you work out the solutions to each of the inequalities?

I didnt understand completely those problem, thats y

Solve them as equations, and since they are <, so you need any answer that is smaller the equality.

cqn you wait, cuz i m gonna show you those.

First one will fit on which one, would it be 2

Note: inequalities have multiple answers.

So but i want to how will i get this answer matching correct answer

Of all of them

that 2 match with this one right?

All does not matched up, thats y, i m asking, how will i figure out all this

If you want, you can pick 2<4.
If you choose now, the rest may or may not work.

Second will be -3, am i right?

I'm afraid not. You have a problem with the sign.

...unless you mean -z>-3

I was saying according that table which i showed

So it suppose to match up with b -3

right?

ok

3z - 5z +10 - 8 <6

3z - 5z +10 - 8 does not look right. Can you check?

2z + 10 - 8 <6
so if this be 2, then other was not 2

I cant really know how to do these all

Problems seems really confusing to me

3z - 5z +10 - 8 <6
is inorrect. it should be +5z and -10. How did you get the signs reversed?

Or written in full
3z+5z-10-8<6

so your saying it would match up with 3, right?

Thats how we find the 3

I mean the \(solution\) to the second inequality is then....?

I m not getting to find all of it exact answer

3z - 10 + 5z - 8 <6
3z + 5z + 10 - 8 <6
8z + 2<6

8z + 2 - 2 <6
8z <6

it will be a 0?

No

Please help!

I dont understand how to solve all this

@CalebBeavers help me please

This one @experimentX

first of all simplify the left side. Can you simplify
\[ -2(1+z) + 4z + 5\]

-2z + -2z + 4z +5
4z +4z +5
8z +5

isnt it?

nope!!

\[ -2(1+z) = (-2) \times 1 + (-2) \times z = ?\]

-2 +2z = -2 (-2) X z =
-2 + 2z = -4 X z
I m stuck :( sorry

-2

\[ -2 \times z = ?\]

-2z

-2 + (-2z)= ?

4z?

no ... you cannot add like that.

|dw:1358353383731:dw|

do you know how to take common?

3x + 3x

|dw:1358353592998:dw|

5x

yes!!

1$ + 2$ = 3$
1$ + 2 pound = 3$
------------------
which of above is correct?

3?

both are same

what is the name of your currency?

pound

okay .. is
1 dollar + 2 pound = 3 dollar ?

no

is that correct?

no

why not?

Both are not similar

So what i did on all that problems, so how do i match because, its seems tricky

it cannot be added

so the bracket one what we need to do

at least you can make it a bit simpler.

-2 + 2z +4z +5
- 2 + 6z +5

?

quite not correct.
+ ( - 2z) = ?

no ...
|dw:1358354499867:dw|

-2z

so 2 match up with this?

I meant, first problem

okay now simplify the first problem.

-2z + 5 < 11

-2z < 6

z < 6/-2
z < -3

it is match up with b

No ... you didn't do it correctly.

divide both side

right?

i forgot, just did one side directly

do you understand the each step?

but am i right with first one?

did you get 2z+3?

no i got -3

if you had done it correctly ... you should have got
\[ z < 4 \]

you are saying it match up 3

right?

thank you :) it making sense now

thank you so much

also if you have any misunderstanding ... don't hesitate to ask.

thats really horrible

first simplify do 2nd and 4 th problem

i think you are capable to do it .. also show me step!!

3z + 5z - 10 - 8 < 6?

yes go on!!

8z - 10 - 8 <6
8z - 2 <6
8z <6 +2
8z < 8
z < 0

http://www.wolframalpha.com/input/?i=3z+%2B+5z+-+10+-+8+%3C+6
watch your second step again.

Sorry so, 8z - 18 < 6
8z < 6 - 18
8z < 12
1.5? :(

8z - 18 < 6
add +18 to both sides.

8z < 24
<3

In third one, how do i start?

watch the example i gave you!!

I m so sorry, i m such a error maker, pls forgive me for all this trouble

in which level do you study?

no actually im in online high school, where i m takin blended course

really? you got terrible math!! these are very very basic simple rules

yes, im ok with other but worse in math

okay try 3

what did you put on 2?

Z + 5 - ( 1 + 6z) > -1

z +5 - 1 + 6z > -1

there you have problem!!
-(1+6z) = -1 times .. what's inside

|dw:1358357567000:dw|

-1 + -6z

what is + - 6z = ?

- 6z

yes ... now simplify it

7z

ok sorry

z + 5 - -1 + -6z <1

it's necessary that you write the whole step on some nontebook.

ok sure, i will keep it mind. z + -6z + 5- + -1
5z + 6 < 1

I know, something wrong in here again

5z < 1 - 6
5z < 5
1

<1

am i wrong?

try pluggin that expression on Wolfram Alpha

I dont know how to do it

:(

your saying negative

how do you do with this
\[ a + 2b - (3a+b) = a + 2b - 3a -b = a-3a+2b-b = -2a +b \]

add by combining like term

how did i get rid of -(3a+b) .. just do it like there.

- 3a + b, we cant go more from this on it

- 3a - b

|dw:1358359171654:dw|

so then your saying it will move to positive

But i didnt understand how did operation + to - at middle

Hows did you change and why?

no ... |dw:1358359302646:dw|

ok

|dw:1358359471738:dw|

not equal

yes

you multiplied - all on Bracket, thats y, everything -

|dw:1358359803427:dw|

- 3a + -2b

tell me in terms of pounds and dollars .... how much should you give to me?

3 dollar, 2 pounds

isn't that equal to -3a-2b? what does this mean?

|dw:1358360151961:dw|

|dw:1358360292451:dw|

|dw:1358360405299:dw||dw:1358360432011:dw|

got it now :) thank you

thats y it was - 1, right

I m extremely sorry for taking your time n making you crazy like this

:( i m so sorry for everything

- 7z - 19 + 19 < 5 +19
-7z + < 24
got long decimal number

you copied the wrong question.
- 7z - 19 + 19 < -5 +19

so first one was right ?

which i showed you b4

no you had +7z ...

-8z - 19 + z > - 5

so -7z + 19 < 5
- 7z + 19 - 19 < 5-19
-7z < 14
z < -2

Thank you so much! im sorry again for trouble :(

I am not in trouble ,,, you might be in math test!! so pratice well!!

yes, i was trying understand these so that i dont make mistake again like this

Last one match up with 2, right, just to be confirmed
