Question

Choose the equation that could be used to find three consecutive integers whose sum is 72.

n + (n + 2) + (n + 4) = 72
n + (n + 1) + (n + 3) = 72
n + (n − 1) + (n − 3) = 72
n + (n + 1) + (n + 2) = 72

Answer 1

so that narrows it down to be either A or B right

Answer 2

Naaah Simpler than that.

Answer 3

its gotta be A

Answer 4

'n' is an integer so is 'n+1' and 'n +2' these add up to 72. Now do the algebra and solve.

Answer 5

A!!!

Answer 6

That should be Ah! Now I've given you the answer (almost) what are the 3 integers?

Answer 7

now im confused

Answer 8

Ok, let's take another example - 3 consecutive numbers add up to 12

Answer 9

Omg im sorry Itin, i read the question wrong. This quesiton came up yesterday :( It said 3 consecutive odd integers last time. my mistake.

Answer 10

so it was B

Answer 11

??

Answer 12

yes B
sorry :c

Answer 13

its cool man

Answer 14

Let's take a 'simpler' example.

n + (n+1) + (n+2) =12
So: 3n +3 =12
So: 3n = 12 -3
So: n= 9/3
So: n = 3
So n+1=?? & n+ 2=?? which gives us the 3 consecutive numbers.

Which are 3,4, and 5.

Answer 15

@ltinson, you tricked me. I could have sworn it said three consecutive ODD

Answer 16

My help was for three consecutive numbers. None of the answers solve for odd numbers.

Answer 17

Maybe not but that's beside the point. Futhermore, I was talking to @ltinson

Answer 18

so it wasnt B?

Answer 19

Hang-on I may be wrong. The caveat is in the question that COULD be used.... my mistake. Badly worded question in my view and you have to solve it to prove that it COULD be B.

Answer 20

The only reason I thought it was B is because I was wrong about it being three consecutive odd. It's not B either

Answer 21

This is not something any of us except the original poster should be confused about. The answer is D.

Answer 22

omg i thought u said it was D

Answer 23

lol, the answer is definitely D. We all goofed up on this one.

Answer 24

Yah... :(
My eyes are failing me today... ugh

Answer 25

Mine too!

Answer 26

B is the only answer that fits the ODD question D the consecutive question.

Answer 27

The answer is D. Tommy, your response doesn't help anyone.

Answer 28

A would have applied to consecutive odds or evens.
D was the answer to this one though.

B was kinda funky, I'm not sure what that would accurately describe.

Answer 29

B doesn't even apply apply to anything at all

Answer 30

Rachael's brother, currently 33 years old, is 3 times Rachael's age 16 years ago. How old is Rachael? Choose the equation that would find Rachael's age, r.

3(33) = 16r
33 = 3(r − 16)
r = 3(33) − 16
r + 16 = 3(33)

Answer 31

I know I set the question - think about it.

Answer 32

A = consecutive even integers
B = applies to nothing
C = applies to nothing
D = consecutive integers

Answer 33

I know I set the question - think about it. Think about it!

Answer 34

No bro, trust me. B and C applies to nothing:

n + (n + 2) + (n + 4) = consecutive even/odd
n + (n + 1) + (n + 2) = consecutive integers

n + (n + 1) + (n + 3) = nothing
n + (n - 1) + (n - 3) = nothing

Answer 35

You're silly if you believe otherwise

Answer 36

can i get help on my problem

Answer 37

I didn't ask for repetitive typing I asked you to think about WHOM set the question bro.

Answer 38

Rachael's brother, currently 33 years old, is 3 times Rachael's age 16 years ago. How old is Rachael? Choose the equation that would find Rachael's age, r.

3(33) = 16r
33 = 3(r − 16)
r = 3(33) − 16
r + 16 = 3(33)

Answer 39

@ltinson, you need to post your new question in a separate thread.

Answer 40

Yeah B

Answer 41

i did

Answer 42

^Exactly why the question should be posted in a new threaad

Answer 43

These questions are an example of critical path analysis - just work then backwards Bro

Answer 44

then=them in this farce ;D
