Can someone confirm my answer for me? i feel like im wrong
When you simplify each side of the equation 4(x + 3) = 5 – (x + 1), you will get the equivalent equation 4x + 12 = -x + 4.
It is not good that correct mathematics is followed by "feel like". If you are sure of your procedure, if you made no error, let's skip the feelings and be confident in the answer. Did you get it right or not?
i really think it is true
That's a start. Now, is it or isn't it? Did you make any errors?

:) see i got the same work you doo now i feel confident in myself lol
can anyone help me solve 1/5n-12=-3? solve for n. I want to learn how to do this
Okay one second.
Do you mean \(\dfrac{1}{5n}\) or \(\dfrac{1}{5}n\)?
the second on that you put
Oh.. Okay one sec.
What's stopping you from Adding 12 and multiplying by 5? You're not "feeling" that it would be wrong, are you?!
give me one second to see hang on
\[1/5 n - 12 = -3 \rightarrow witch means \rightarrow n/5 - 12 = -3 \rightarrow so \rightarrow n/5 -12 + 12 = -3 + 12 so n = 45.\]
Crap it got cut off :( N = 45.
do you feel like helping me on a few more? if not its cool...
n - - 12 + 12 = -3 + 12 5 So: n - = 9 = N = 45 5 Sure.
ok give me a sec, im gouing to see if I can do them real quick
@zzr0ck3r ;) im just not good at math...
Solve the combined inequality and select the answer that best describes the graph of the solution. 3x – 7 > -10 and 5x + 2 < 22
a.)open dot at -1, open dot at 4, and shaded between the numbers b.)closed dot at -1 and 5, shaded between the numbers c.)closed dot at 1, open dot at 5, and shaded between the numbers d.)none of the above
4x+12=5-x-1 4x+12=4-x 5x=-8 x=-8/5 <---- answer
so then the answer would be "none of the above"
make sure the question posted is correct
linear equations should either have no solution or one solution
Solve the combined inequality and select the answer that best describes the graph of the solution. 3x – 7 > -10 and 5x + 2 < 22 a.)open dot at -1, open dot at 4, and shaded between the numbers b.)closed dot at -1 and 5, shaded between the numbers c.)closed dot at 1, open dot at 5, and shaded between the numbers d.)none of the above
ahhh, i was reading the first posted and not seeing how it correlated to this one
tell me what you got for your solution to chk with
ok hang on im still trying to solve it. give me on more sec
i got x>-1 or x<4 so i would choose A for my correct answer?
ok thankyou... i have one more and this one is a bit trickey there are several parts to it...would someone mind helping me out? I would like to know how to do thiss
ok, it says AND so that is correct
ok give me one second :)
A.) 2(x – 4) + 5x = -22 B.)2(x – 3) – 17 = 13 – 3(x + 2) C.)2/3X+6=10 D.)|2x + 4| = 10 E.)Solve for y: 2x – 3y = 6 F.)The sum of three consecutive EVEN integers is 42. What are the integers? (Name all three integers.) G.)Solve the inequality: -2x – 6 < 4. Be sure to provide the solutions, describe the circles and the shading for the graph. H.)Please solve the combined inequality and describe the graph. 3x-6 > -3 and 3x-6 < 12
each letter is a seperate question.
thats not "one more"; thats several more :/
I didnt realize that they were seperate, until i started to read them. if you cant help, then its cool...
I think F might be the only one that you might not be familiar with
can you think of a general set of 3 consecutive numbers?
consecutive even numbers that is
every even number is a multiple of 2 2*1=2 2*2=4 2*3=6 2*4=8 .... 2n = even integer
if we want 3 consecutive even integers; we could write it like this: 2n-2, 2n, 2n+2 to add these up we have 2n-2 + 2n + 2n+2 = 3*2n = 6n for what value of n does 6n = 42 ??
good, then our middle number has to be 2*7=14 12+14+16 = 42 right?
yes, i just got that! :) thankyou!! could u help me on G? and i promise thats it lol
Solve the inequality: -2x – 6 < 4 got tell me what you
touchpad is touchy :)
lets chk -2x – 6 < 4 +6 +6 ----------- -2x < 10 /-2 /-2 ------------ x > -5 ; remember what the negative does to us
shoot i did forget that lol, thanks for remidning me
open or solid, which would you pick and why?
and i got x<6 for the other one open
there is no other one on G and open is correct; why open?
crap see my ADD is messing me up!!! haha, im sorry!! but open because its what it equals?
if we see what the question is asking for > or < these notations have no "=" associated with them; a closed circle represent the "=" part
x > -5 ; no equal, no solid <----0========> -5
