Question

The sum of three consecutive numbers is 99 what is the smallest of the three numbers?

Answer 1

I would say 33.

Answer 2

ok thank you so much :)

Answer 3

I don't think that'll work
Let x= the smallest integer
x+1= next integer
x+2= the next,next integer
Now you have the three consecutive integers and we know the sum is 99


So
x+x+1+x+2=99
Can you solve for x?

Answer 4

no haha I don't get it lol

Answer 5

Ok.. What part don't you get?

Answer 6

where I have to slove for x

Answer 7

So you get the equation though?

Ok you have
x+x+1+x+2=99
Do you know how to combine like terms?

Answer 8

eh not so much

Answer 9

Ok. I'll break it up for you.
So lets just focus on the right side.
I'm gonna rearrange so like terms are together

x+x+x+1+2
So (x+x+x)+(1+2)
What's x+x+x?
And what's 1+2?

Answer 10

ok so im thinking x means 1 and 1+2 =3 srry if im wrong

Answer 11

Yes. 1+2=3
And another way of writing x is 1x..so
1x+1x+1x=?

Answer 12

3x

Answer 13

Yes.
So now can you rewrite x+x+1+x+2=99 by simplifying the left side(combining like terms)

Answer 14

ok I got stuck again srry

Answer 15

Rearranging
You can x+x+x+1+2=99
And breaking it up like we did above, what will out left side look like now?

Answer 16

um 9x?

Answer 17

9x = 99 yea or no

Answer 18

3x+3=99
Do you see how I got this?

Answer 19

oh yes I see now so that is the answer

Answer 20

Now you want solve for x.
To start you can subtract 6 on both sides

Answer 21

ok I know im suppose to subtract 6 from 99 but on the other side would I subtract 6 from 3x or 3 im thinking 3 but idk your the smart one here lol

Answer 22

3x+3=99
-3. -3
--------------
3x=96. Remember 3-3=0
Does this make sense?

Answer 23

yes keep going lol

Answer 24

Now can you divide both sides by 3? What do you get?

Answer 25

Oh my bad. It was suppose to say 3 not 6. Sorry if I was misleading you or something up there

Answer 26

oh no it's ok

Answer 27

a simple method is divide the number by 3... them its the 2 integers either side of the answer.


99/3 = 33 so the numbers are 32, 33, 34

Answer 28

Let the smallest of them be x. The numbers will be x, (x+1), and (x+2) respectively.

Answer 29

Since their sum is 99, x+(x+1)+(x+2)=99

Answer 30

Understand this part?

Answer 31

not really

Answer 32

If the smallest of them is x, then the next is x+1

Answer 33

Actually asking question is an essential part to learning

Answer 34

Therefore you should ask more questions

Answer 35

Where do you not get?

Answer 36

"The numbers will be x, (x+1), and (x+2) respectively." or "Since their sum is 99, x+(x+1)+(x+2)=99"?

Answer 37

x=32

Answer 38

You said you couldn't get it, therefore I need to help you understand the concept

Answer 39

nah im ok now thank you so much

Answer 40

no problem
