55.)find two consecutive odd integers whose sum is 628??
56.)find three consecutive integers whose sum is -1,230
57.)find three consecutive integers whose sum is -198
58.)find three consecutive odd integers whose sum is 339
59.)find three consecutive even integers whose sum is 342?

Answer 1

55.)find two consecutive odd integers whose sum is 628

let x = first number

so x+2 is the next consecutive odd integer

adding them and setting the sum equal to 628 gives us

x+x+2 = 628

2x+2 = 628

2x = 628-2

2x = 626

x = 626/2

x = 313

x+2 = 313+2 =315


Therefore, the two integers are 313 and 315

Answer 2

thanks @jimthompson

Answer 3

you're welcome

Answer 4

@jimthompson would u like to have medal or no??? your choice

Answer 5

either way is fine

Answer 6

help w/next one just need two equations u use to solve???? i can rest

Answer 7

find three consecutive integers whose sum is -1,230

let x = first integer, so x+1 is the next consecutive integer and x+2 is the next one

add them up, set them equal to -1230 to get


x+x+1+x+2 = -1230

Answer 8

3x+5=1230

Answer 9

right? @jim_thompson5910

Answer 10

close

Answer 11

x+x+1+x+2 = -1230

3x+3 = -1230

Answer 12

keep going

Answer 13

x=409 for first x what do i do for 2nd x and 3rd x?

Answer 14

3x+3 = -1230

3x = -1230-3

3x = -1233

x = -1233/3

x = -411

Answer 15

x = -411

x+1 = -411+1 = -410

x+2 = -411+2 = -409


so the three integers are: -411, -410, -409

Answer 16

thanks. help w/ next one???

Answer 17

I may be able to help u with the next one, once you share the problem with me.

Answer 18

I'll set it up, but let you finish

Answer 19

ok

Answer 20

okay jim then you can take over. I won't bump in.

Answer 21

57.)find three consecutive integers whose sum is -198


x = first number
x+1 = next consecutive number
x+2 = next consecutive number


add up the 3 numbers and set it equal to -198

x+x+1+x+2 = -198

solve for x


and tejeshwar95, you can help as much as you want

Answer 22

well, okay... but it seems to me that you got this. but will ask away whenever u need help

Answer 23

how do u do the just x one/????

Answer 24

1st step on equation??????

Answer 25

Just add the three numbers that is x + x +1 + x + 2 = -198

Answer 26

When you ask for the first step, that is where the question ends.

Answer 27

practically speaking.

Answer 28

if i could id give u both a best response u guys have been sooo much help

Answer 29

who would rather have a best response more??? if u care

Answer 30

Do u want another question like this for practice sake?

Answer 31

58 and 59 idk how to set up three equations that's all i need?

Answer 32

Give it to the other guy, he is the main guy, I merely butt in so.... I don't really deserve it.

Answer 33

couldone of u hep with 58 and 59??

Answer 34

Okay, this is really easy.
Assume a number x

Answer 35

now count the distance between two odd numbers

lets say the odd numbers are 1 and 3

Answer 36

now try to form the equation. Its okay to do it wrong, but its important to do it.

Answer 37

please @tejeshaw95 look at how @jimthompson explained it u don't make any sense to me?????

Answer 38

if u just gave me equations w/out explaining it. that's NOT cheating

Answer 39

okay. Lemme explain it in a bit more detail. I was actually hoping you would take the hint and run with it. But, its okay.

well,
lets assume that the odd numbers we are talking about are 1,3,5. Now, these are what are called consecutive odd numbers.
now see the difference between two consecutive odd numbers.
3-1 = 2
5-3 = 2
Now we all know that 1+3 + 5 is not = to 339.
So, now, lets assume the first number to be x. So, the number following it would be x + 2 since that is the difference or gap between two consecutive odd numbers. And the odd number after the 2nd odd number which was x+2 is x+2+2 which is x+4.
So, now we add em
we get x+ (x+2)+(x+4)
now, the sum of these three numbers is 339. So, now u solve the equation.

Answer 40

Consecutive means one after the other. so three consecutive numbers can be 1,2,3. Two consecutive even numbers can be 0,2,4 and two consecutive odd numbers can be 1,3,5.

Answer 41

3x+1+5=339 ??????

Answer 42

2nd equation above could it be written that way??

Answer 43

you are technically wrong but, right.

actually it should've been 3x+2+4

Answer 44

Lemme give you something easier to help u understand the concept.

Find three consecutive numbers whose sum is 6.

Answer 45

I got 111 please help w/1st and third equation. 2+2+2=6 Are u allowed to just give me 1st and third equation????

Answer 46

If I give you the equation, the question reaches its end. The trick lies in forming the equation.
No, consecutive doesn't mean the same numbers. It has to be three different numbers.

Answer 47

2+3+1

Answer 48

yes. that is correct.

Answer 49

how does that help w/58???? or 59

Answer 50

because it is the basic concept that allows you to solve the question.

You are too focused on finding the answer to the question to such an extent that you are missing out the underlying concept.

Answer 51

I am giving you the concept so u can solve millions of such problems without any help, and trust me that is a great feeling.

Answer 52

I know the problem and how many answers u need to find. and I know how to solve equations. I just don't know what the equations are. I understand what ur saying. its just like when jimjohnson helped iwas learning and starting to understand he gave me equations and step by step and I was starting to get it.. now u wont imstarting to not comprehend as well

Answer 53

I have 5 more questions after I get 58 and 59 understood

Answer 54

please reply????? @teleshaw95

Answer 55

@tejeshwar95 plz reply?

Answer 56

Oh, I see what you want.

58.)find three consecutive odd integers whose sum is 339
let x = first number

so x+2 is the next consecutive odd integer
and x+4 is the odd integer after that

adding them and setting the sum equal to 628 gives us

x + (x+2) + (x+4) = 339

x + x + x + 2 + 4 = 339

3x = 339-2-4

3x = 333

x = 111

x = 111

x +2 = 111+2 =113

x + 4 = 111 + 4 =115

Answer 57

oh btw u got x right. Now you just gotta add the 2 for the second number and 4 for the third number.
Sorry, my bad, I hadn't calculated the answer then.

Answer 58

that explaining was perfect all I need is equation 1st line tho per equation.. 59??? do same way pleaseeeeee???????

Answer 59

okay

Answer 60

asap pleaseeee

Answer 61

59.)find three consecutive even integers whose sum is 342?

let x = first number

so x+2 is the next consecutive even integer
and x+4 is the even integer after that

adding them and setting the sum equal to 342 gives us

x + (x+2) + (x+4) = 342

x + x + x + 2 + 4 = 342

3x = 342-2-4

3x = 336

x = 112

x +2 = 112 +2 =114

x + 4 = 112 + 4 =116

Answer 62

I got 112 and 116 what did x=?

Answer 63

x = 112,
x+2 = 114,
x +4 = 116
