Here's to testing your IQ.
Ok, Crimson and INightmareI are kinda young so you won't be expected to answer this(I went to a tutoring school but mostly my dad taught me algebra):whistling:
Maybe people in their older 20s etc. should be able to answer.
By the way I am 10 years old and I DID NOT search this up
I did it last year
Enjoy
Mr.Santos kept ants and spiders as pets(what a WEIRDO!).
He counted about 15 heads and 98 legs in total
How many ants and
how many spiders

Post Your Answers DOWN v
P.S Trial and Error is NOT algebra:prophet:

15 ants and spiders
HMHMHMHMH
How did you do it?*trollface*
Set it out like
x+y=?
yz=?
etc.
And HOW MANY of EACH like x ants and y spiders

Nope
If it was that easy a 2 year old could answer it:whistling:
Like how many of EACH

Ants have 6 legs and spiders have 8?
11 ants and 4 spiders if I have the legs right!

ant = 1 head and 6 legs
spider = 1 head and 8 legs
15 heads= 15 ants and spiders
98/6 = 16 r2
98/8 = 12 r2
....I'm not sure what to work out next :sweatdrop:
I think some of my classmates know how to do it, how do you do it? I want to learn :)
Ok so
let's assume that x is ants and y is spiders and these are the only facts as listed below.
x+y=15
6x(6 legs on ants)+8y(8 legs on spiders)=98
15y=x
So we put it into the other equation.
6(15y)+8y=98
(We don't put a multiplication sign in algebra because then it gets confusing:confused:)
So we times both of the numbers inside the brackets because it has to or it won't be fair(I sound like a child)
so
906y+8y=98
90+2y=98
y=4
now we subtract 4 from 15
=11
11=x
that means
11 ants and
4 spiders
Geddit?
You will if you practice again...
and again...
and again...
until the end of time...jk
just a lot of times:sweatdrop:

In Ireland we do that a different way using quadratic equations.

You'll learn it when your older. Much harder than algebra.

Stop making others do your home work ;)
When I was 12 I got a high distinction in math.
I was in the top 3% of my state. Still got the certificate in its frame.
Now, I am not so good at maths. They say "use it or lose it" if you don't keep your mind active, you start to forget these things.
If I absolutely have to do it, I will. But I sure as hell wouldn't do it for fun/voluntarily (aka this question.) Occasionally ill do it for an IQ test or this mensa app I've got.
Or a real life problem, which occurs very rarely.
Those online IQ tests totally overvaluate your intelligence.
Just like how some stores label an item of clothing a size smaller than it actually is, flattery equals revenue apparently.
Ill take a stab at it.
11 ants
4 spiders
4 x 8 = 32 spider legs
11 x 6 = 66 ant legs
66+ 32= 98 legs total and 15 heads

Not many people use algebra in their daily lives(besides scientists and mathematicians).

I'm In GSP In My Grade,So We Do Beginner Algebra Equations.Its Called 'Hands On Equations',And Its Actually Kinda Easy. :]

I betcha no algebra in that test:ninja:
and I did that problem last year
part of
'Intensive Training'
to get into the best public school in QLD
aka
Brisbane State High School:sweatdrop:
I passed
Top 10 percent in maths(high as it would go)
And well,
that was Trial and Error...
because HOW did you get (so and so):confused:
Meh. who cares:whistling:

Hehe, love seeing when youngins learn new things. They like to show off I suppose. Or to see what others think, hehe. I am great at maths, but I don't do it for fun,heh. Try doing Literal Equations. Those are fun!
