satelitte??????

Answer 1

polpK? CAN U HELP ME?

Answer 2

with?

Answer 3

the sum of two consecutive odd integers is 52 . find the integers I have to be to scholl in 30 min.

Answer 4

school

Answer 5

Well, you know that two consecutive 'odd' integers will be 2 units apart from eachother..

1,3,5,7,etc

Each one is 2 more than the previous one. So lets let x be the first one. The next one must be x+2 then.

So we have:

\[x + (x+2) = 52\]

Answer 6

And now we're back to the problem of solving an equation..

Answer 7

unfortuantly,

Answer 8

But this one isn't too bad..

\[x + x + 2 = 52\]

So what is x + x ?

Answer 9

ok

Answer 10

2x

Answer 11

Right.

So we have:
\[2x + 2 = 52\]

Answer 12

POLPAK!!! Can you help me next? I desperately need lin algebra help!

Answer 13

Now subtract 2 from both sides of the equation.

2x + 2 = 52
- 2 -2
-----------

Answer 14

Polpak ill finish off here.. I know this stuff.

Answer 15

I can try yes bahrom.

Answer 16

Did you post your question already?

Answer 17

Okay roseanne:
2x + 2 - 2 = 52-2
2x + 0 = 50
2x = 50
divide both sides by 2:
2x/2 = 50 / 2

Answer 18

ok

Answer 19

I did polpak it's Linear ALGEBRA!!

Answer 20

x = 50 / 2 = 25

Answer 21

So 2x = 50

What times 2 is 50? Must be 25. So if x is 25, and that's the first odd integer, what is the next one?

Answer 22

x=25 because you divided then by 2

Answer 23

yes

Answer 24

I dont know whats the other one?

Answer 25

so thers two #'s polpak?

Answer 26

Well first number is 25, the next one is 25+2 = 27

Answer 27

Since consecutive odd integers are:
x, x+2, (x+2)+2, [(x+2)+2]+2, and so on..

Answer 28

isnt 27 sopossed to divive into 52?

Answer 29

No.. it says the sum of two odd consecutive integers.. Sum means PLUS:
25 + 27 = 52
See 25 and 27 are consecutive odd integers and their sum is 52

Answer 30

so whats my answer x= 27 and x= 25?

Answer 31

yes that is your answer.

Answer 32

the two numbers are 25 and 27

Answer 33

thank you so much~!!!!!!

Answer 34

np polpak did most of the work anyway..

Answer 35

I know he or she is very good!!!!!

Answer 36

how are you getting along with this algebra? more equation solving

Answer 37

can u help me?>>??? satellite?

Answer 38

sure ask away

Answer 39

She needs help solving equations. Unfortunately she hasn't spent enough time practicing and understanding how it's done.

Answer 40

The sum of two consecutive integers is 85 find the integers im getting more and more knowledge everyone is helping me so much!!!!!!

Answer 41

Everything else she does fine, but with solving equations she gets flummoxed and doesn't know where to go or what to do.

Answer 42

i remember from yesterday. we go slow

Answer 43

first thing we can do before solving an equation is guess. it is clear what "consecutive integers" means yes?

Answer 44

like say 40 and 41

Answer 45

but of course 40 and 41 are not your answers, because 40+41 = 81 and you want 85

Answer 46

so maybe we can just make another guess before we do the algebra. nothing wrong with knowing the answer before you start.

Answer 47

@rosanne you want to make another guess of two consecutive integers that add to 85?

Answer 48

I hAVE school at 1130 but i have acouple more probs

Answer 49

I have to hurry

Answer 50

42?

Answer 51

ok 42 and 43 are consecutive yes? and they add to 42+43=85 yes? so you win. done

Answer 52

if you want algebra you can write
\[n+n+1=85\]
\[2n+1=85\]
\[2n+1-1=85-1\]
\[2m=84\]
\[\frac{2n}{2}=\frac{84}{2}\]
\[n=42\] but you got it by thinking, which is better

Answer 53

sometimes it is harder to guess than to do the algebra but sometimes it is easier to guess and check

Answer 54

ok

Answer 55

one more or do you have to run to school?

Answer 56

i need help!

Answer 57

? @scilaaax last one i think

Answer 58

yes the perimeter of a traingle is 54 m the lengths of the sides are represented b y three consecutive even integers find the lengths of the three sides

Answer 59

ur right <3

Answer 60

consecutive EVEN integers, like 8, 10 and 12 yes?

Answer 61

algebra or guess?

Answer 62

huh?? you know more im not sure

Answer 63

question is do you want to solve
\[n+n+2+n+4=54\] or do you just want to pick an even number and see if it works?

Answer 64

i could pick 10 and then the even numbers would be 10 + 12 + 14 = 36 but that is not good because i want 54 not 36. so then i would pick a number higher than 10. or you could solve the equation i wrote.

Answer 65

someone help ! sorry to intrude . :)

Answer 66

@tabbey just post and you will get an answer in under a minute i am sure

Answer 67

@rosanne still here?

Answer 68

yes we can pick an even number

Answer 69

ok go ahead and pick on bigger than 10
