Question

Can someone confirm my answer for me? i feel like im wrong

Answer 1

When you simplify each side of the equation
4(x + 3) = 5 – (x + 1), you will get the equivalent equation
4x + 12 = -x + 4.

Answer 2

i pick true

Answer 3

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?

Answer 4

i really think it is true

Answer 5

That's a start. Now, is it or isn't it? Did you make any errors?

Answer 7

Its true. :)

Answer 8

:) see i got the same work you doo now i feel confident in myself lol

Answer 9

can anyone help me solve 1/5n-12=-3? solve for n.
I want to learn how to do this

Answer 10

That's the spirit.

Answer 11

Okay one second.

Answer 12

Do you mean \(\dfrac{1}{5n}\) or \(\dfrac{1}{5}n\)?

Answer 13

the second on that you put

Answer 14

Oh.. Okay one sec.

Answer 15

What's stopping you from Adding 12 and multiplying by 5? You're not "feeling" that it would be wrong, are you?!

Answer 16

give me one second to see hang on

Answer 17

\[1/5 n - 12 = -3 \rightarrow witch means \rightarrow n/5 - 12 = -3 \rightarrow so \rightarrow n/5 -12 + 12 = -3 + 12 so n = 45.\]

Answer 18

Crap it got cut off :( N = 45.

Answer 19

do you feel like helping me on a few more? if not its cool...

Answer 20

n
- - 12 + 12 = -3 + 12
5

So:

n
- = 9 = N = 45
5

Sure.

Answer 21

ok give me a sec, im gouing to see if I can do them real quick

Answer 22

@zzr0ck3r ;)
im just not good at math...

Answer 23

Solve the combined inequality and select the answer that best describes the graph of the solution.
3x – 7 > -10 and 5x + 2 < 22

Answer 24

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

Answer 25

4x+12=5-x-1
4x+12=4-x
5x=-8
x=-8/5 <---- answer

Answer 26

so then the answer would be "none of the above"

Answer 27

make sure the question posted is correct

Answer 28

linear equations should either have no solution or one solution

Answer 29

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

Answer 30

ahhh, i was reading the first posted and not seeing how it correlated to this one

Answer 31

tell me what you got for your solution to chk with

Answer 32

ok hang on im still trying to solve it. give me on more sec

Answer 33

i got x>-1 or x<4
so i would choose A for my correct answer?

Answer 34

i agree

Answer 35

but hold on

Answer 36

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

Answer 37

ok, it says AND so that is correct

Answer 38

post it up

Answer 39

ok give me one second :)

Answer 40

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

Answer 41

each letter is a seperate question.

Answer 42

thats not "one more"; thats several more :/

Answer 43

I didnt realize that they were seperate, until i started to read them. if you cant help, then its cool...

Answer 44

I think F might be the only one that you might not be familiar with

Answer 45

thankyou

Answer 46

can you think of a general set of 3 consecutive numbers?

Answer 47

consecutive even numbers that is

Answer 48

4,5,6?

Answer 49

every even number is a multiple of 2

2*1=2
2*2=4
2*3=6
2*4=8
....
2n = even integer

Answer 50

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 ??

Answer 51

7

Answer 52

good, then our middle number has to be 2*7=14

12+14+16 = 42 right?

Answer 53

yes, i just got that! :) thankyou!!
could u help me on G? and i promise thats it lol

Answer 54

Solve the inequality: -2x – 6 < 4
got
tell me what you

Answer 55

touchpad is touchy :)

Answer 56

x<5

Answer 57

-5*

Answer 58

lets chk

-2x – 6 < 4
+6 +6
-----------
-2x < 10
/-2 /-2
------------
x > -5 ; remember what the negative does to us

Answer 59

shoot i did forget that lol, thanks for remidning me

Answer 60

open or solid, which would you pick and why?

Answer 61

and i got x<6 for the other one
open

Answer 62

there is no other one on G

and open is correct; why open?

Answer 63

crap see my ADD is messing me up!!! haha, im sorry!! but open because its what it equals?

Answer 64

if we see what the question is asking for

> or <

these notations have no "=" associated with them; a closed circle represent the "=" part

Answer 65

no equal, no solid

Answer 66

ohhh that makes sense

Answer 67

i didnt know that

Answer 68

x > -5 ; no equal, no solid

<----0========>
-5

Answer 69

thankyou!!!!
