Algebra 1 World problems systems of equations.
Manny, Moe, and jack drove 168 miles. If Manny drove twice as far as Jack and Moe Drove three times as far as Jack, how far did Jack drive?

Really need help

anonymous · Answer

plz help

anonymous · Answer

hang on let me see if something works real quick

hero · Answer

x + y + z = 168
x = 2z
y = 3z

2z + 3z + z = 168

anonymous · Answer

If it was 168 why did my teacher put 60 instead. o.o

hero · Answer

It says they drove a total of 168 miles

anonymous · Answer

Should I believe you guys more ? Or my teacher is incorrect

hero · Answer

That's the first sentence

anonymous · Answer

Okay the answers ends up being -- Jack drove 28 miles. How I did it: A (manny) + B (moe) + C (jack) = 168. The problem states that Manny drove twice as far as Jack so A = 2C. Moe drove three times as far as Moe, so B = 3C. You now fill A and B in creating this equation: 2C + 3C + C = 168. Combine like terms making it 6c = 168, divide by 6, there's your answer.

@mariannu, you are confused

anonymous · Answer

I know But this is what he did x+x+1+x+2=60

hero · Answer

Well, that's wrong

anonymous · Answer

he got an answer of x=9

hero · Answer

Are you sure that's a teacher or an imposter?

anonymous · Answer

Maybe he did not realize he put 60 because sometimes he would do the equation to fast and he would make an error sometimes. NOt often

hero · Answer

No, the entire setup is wrong. I think you may have confused which problem the teacher was solving.

anonymous · Answer

I'm still confused.

hero · Answer

Well, that's probably your teacher's fault

anonymous · Answer

hmm ok XD I will just do it your way I guess. XD Thanks though.

hero · Answer

What's your teacher's phone number? I will call him and explain to him what the correct answer is.

anonymous · Answer

I wonder where the hell he got that equation. o.o Usually can keep up with his fast paste.XD

anonymous · Answer

I will just go to him tomorrow morning and tell him about it And thank you. ^.^ Both of you guys.

anonymous · Answer

No its ok. No need too. I can tell him, but thanks though for your generosity . ^.^

anonymous · Answer

And plus I don't know his number anyways.

hero · Answer

Maybe your teacher copied the wrong solution from the answer book.

anonymous · Answer

hmm probably. but thanks ^.^
