Are children given excessively hard questions?

x - 19 + 17 = 63
x - 2 = 63
x = 65

Jesus Veeky Forums seriously? This section 1.1 of pre-algebra.

holy shit it's 65

it's 46

its 40

61 now stop posting this stupid threads

You're not considering order of operations.

Could you explain why?

See you ignore the 19 they r red herring (presumably) so 63-17=46

>It's a Veeky Forums can't do basic arithmetic episode

youre meant to ignore the 19

The answer is 0, the train began empty when it was first finished conduction

This.

>youre meant to ignore the 19
Only if "to begin with" means AFTER the first stop.

For what purpose? The problem doesn't state "19 people get off in the train at the first stop."

you get the wrong answer if you don't ignore it. correct answer is 46

steel yourselves Veeky Forums

This one's a doozy

60 degrees

60 degrees

>you get the wrong answer if you don't ignore it.
Still want to know why you ignore it.

Ok, you're not even trying anymore.

They're not a red herring. Your knowledge of there being 63 people on the train is dependent upon the 19 who got off and the 17 who got on. Therefore, it's 65.

>multiple choice math exam

Simple addition

It's pi/6 radians. If you answered otherwise, you're the reason China is beating us.

Poor quality b8

Divide the coin into 12 triangles ( r + r + s = Triangle circumference; is an isoceles triangle)
360°/12 = 30° is therefore the angle between the r's.

(180°-30°)/2 = 150°/2 = 75° is the angle between an r and s

75° * 2 = 150° is the bigger angle between the floor and the first side of the coin

180° - 150° = 30° is the smaller angle between the floor and the first side of the coin.

We can flip this up and multiply by 2 to get our answer 30°*2=60°

The sum of the exterior angles of a convex polygon is 360°.

360° / 12 = 30 °

30° * 2 = 60°

Degrees are more useful because 360 can be quickly mentally subdivided. Same reason feet and inches beat meters and centimeters.

off-on=Δ
(19)-(17)=2
63+Δ=Ans
63+(2)=65

t. literal underage

tbf, 5 options, no calculator, though that wouldn't help really, and somehow it can be quite a hard paper

Look up the UK maths challenge for them... granted that question was stupid easy for their standards.

Other one to check is the UK STEP maths papers

but he's correct

you can't just use the triangle as your variable. thats reserved for rise over run

>Obvious equilateral triangle
I wonder what the angles could be?

Most hilarious thing about that is the bitch saying "The answer is 46 because the answer key says so."

Are teachers these days retarded? If the answer key say 0-0=1 would they go along with?

I think they may have intended the question to be "How many of the people who are on the train now were on the train to begin with?"

In that case the answer is 46.

x=starting quantity of people
x=63+19-17

wew lad, there were 65 people on the train at first. :^) Totally hard, can't imagine a second grader doing that, that is practically real analysis and sheeit.

My trig teacher called me out for always using degrees. Literally that's how he would reference me.
I asked him if his mind automatically translated the face of a clock into radians.

>yfw it's actually [math]\pi/3[/math] radians

thank god this one wasn't in the US, we've taken enough abuse

>to begin with
Is the begin state the state before the first stop or when?

In the beginning 65 people enter, then 19 leave at first stop while 17 leave.

If the answer is supposed to be 46, then isn't it worded in a very wrong way?

It's from the further maths exam in Australia. Further maths is the third tier, and is basically designed for retards. Also, I'm pretty sure only the first 1/3 or so of the exam is multiple choice

So, anyone here who managed to find out how the supposedly correct solution, 46, comes about?

This twitter feed is fucking hilarious.
Soccer moms getting sad they can't do basic math when they got the answer right.
46 kek

It's always been like this and always will.

The answer is 1 or zero depending on what you define as t=0/the start.

>tough question

65 idiots

>Being mad about someone solving it faster

Well done

I hate how many math problems during up to high school are just worded very badly and you can very easily understand the question wrong.

If you do mathematics beyond that you will never have to figure out vaguely stated question because that is against everything maths represents.
There is no vagueness in maths everything is defined and understanding a question wrong is very hard.

Everyone here (except for the trolls) understood that it was 65.

The question was not ambiguous.

x - 19 + 17 = 63
