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?

can anyone help me solve 1/5n-12=-3? solve for n. I want to learn how to do this
tkhunny
  • tkhunny
That's the spirit.
anonymous
  • anonymous
Okay one second.
tkhunny
  • tkhunny
Do you mean \(\dfrac{1}{5n}\) or \(\dfrac{1}{5}n\)?
anonymous
  • anonymous
the second on that you put
anonymous
  • anonymous
Oh.. Okay one sec.
tkhunny
  • tkhunny
What's stopping you from Adding 12 and multiplying by 5? You're not "feeling" that it would be wrong, are you?!
anonymous
  • anonymous
give me one second to see hang on
anonymous
  • anonymous
\[1/5 n - 12 = -3 \rightarrow witch means \rightarrow n/5 - 12 = -3 \rightarrow so \rightarrow n/5 -12 + 12 = -3 + 12 so n = 45.\]
anonymous
  • anonymous
Crap it got cut off :( N = 45.
anonymous
  • anonymous
do you feel like helping me on a few more? if not its cool...
anonymous
  • anonymous
n - - 12 + 12 = -3 + 12 5 So: n - = 9 = N = 45 5 Sure.
anonymous
  • anonymous
ok give me a sec, im gouing to see if I can do them real quick

Solve the combined inequality and select the answer that best describes the graph of the solution. 3x – 7 > -10 and 5x + 2 < 22
anonymous
  • anonymous
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
anonymous
  • anonymous
4x+12=5-x-1 4x+12=4-x 5x=-8 x=-8/5 <---- answer
anonymous
  • anonymous
so then the answer would be "none of the above"
amistre64
  • amistre64
make sure the question posted is correct
amistre64
  • amistre64
linear equations should either have no solution or one solution

ahhh, i was reading the first posted and not seeing how it correlated to this one
amistre64
  • amistre64
tell me what you got for your solution to chk with
anonymous
  • anonymous
ok hang on im still trying to solve it. give me on more sec
anonymous
  • anonymous
i got x>-1 or x<4 so i would choose A for my correct answer?
amistre64
  • amistre64
i agree
amistre64
  • amistre64
but hold on
anonymous
  • anonymous
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
amistre64
  • amistre64
ok, it says AND so that is correct
amistre64
  • amistre64
post it up
anonymous
  • anonymous
ok give me one second :)
anonymous
  • anonymous
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.
amistre64
  • amistre64
thats not "one more"; thats several more :/
anonymous
  • anonymous
I didnt realize that they were seperate, until i started to read them. if you cant help, then its cool...
amistre64
  • amistre64
I think F might be the only one that you might not be familiar with
anonymous
  • anonymous
thankyou

  • amistre64
can you think of a general set of 3 consecutive numbers?
amistre64
  • amistre64
consecutive even numbers that is
anonymous
  • anonymous
4,5,6?
amistre64
  • amistre64
every even number is a multiple of 2 2*1=2 2*2=4 2*3=6 2*4=8 .... 2n = even integer
amistre64
  • amistre64
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 ??
anonymous
  • anonymous
7
amistre64
  • amistre64
good, then our middle number has to be 2*7=14 12+14+16 = 42 right?
anonymous
  • anonymous
yes, i just got that! :) thankyou!! could u help me on G? and i promise thats it lol
amistre64
  • amistre64
Solve the inequality: -2x – 6 < 4 got tell me what you
amistre64
  • amistre64
touchpad is touchy :)
anonymous
  • anonymous
x<5
anonymous
  • anonymous
-5*
amistre64
  • amistre64
lets chk -2x – 6 < 4 +6 +6 ----------- -2x < 10 /-2 /-2 ------------ x > -5 ; remember what the negative does to us
anonymous
  • anonymous
shoot i did forget that lol, thanks for remidning me
amistre64
  • amistre64
open or solid, which would you pick and why?
anonymous
  • anonymous
and i got x<6 for the other one open
amistre64
  • amistre64
there is no other one on G and open is correct; why open?
anonymous
  • anonymous
crap see my ADD is messing me up!!! haha, im sorry!! but open because its what it equals?
amistre64
  • amistre64
if we see what the question is asking for > or < these notations have no "=" associated with them; a closed circle represent the "=" part
amistre64
  • amistre64
no equal, no solid
anonymous
  • anonymous
ohhh that makes sense
anonymous
  • anonymous
i didnt know that
amistre64
  • amistre64
x > -5 ; no equal, no solid <----0========> -5
anonymous
  • anonymous
thankyou!!!!
