Ok translation for both
10)
a and b are natural numbers
if so what is the remaining number from (a-b)/6
11)
a b and c are natural numbers
if so what is the lowest value for "a"?

woat


lowest value right
maybe just plug and chug like darp said and then solve backwards to see how you can get the answer
if a = 5b + 3, b = a-3 / 5 but one of the options - 3 is divisible by 3 execept A and D
@whole scaffold
and C = a-28 / 30
a = 5(6c+5)+3
solve for c
a = 30c + 25 + 3
c = (a-28)/30
its a-28
now from A and D we see that 158-28 is 130 which is NOT divisible by 30 but 208-28 is 180 which IS divisible by 30
Plug and chug
drunk old people :
Give me one good reason why not
these are called diophantine equations @whole scaffold
there's more than 1 solution
so you can't plug and chug
there's a more elegant way as well
Called bezouts lemma
He has 4 answers and one is correct
but let's not go down that lane
You must've been good at arithmetic because I'm bad at addition
I use calculators for basic multiplication
generally if ax+by = c then gcd(a, b) should divide c
use this
1=-1 great job
a=5b+3
b=6c+5
For a=158
(158-3)/5=b
155/5=b
professional chugger
Result:
31
Funny number in your country?
what.
Find c
👍
It comes down to the value of c
You have 2 equations and 3 unknowns
Plug and chug
Enough time
wyafey
u guys r still studying
eren math version
lol
translate the question @whole scaffold
My boy counting fingers to divide
Just dont divide 390 by 13 using fingers please
When you did a-b
i don't think the eq is right
parametric on n
its definitely more than 32
now
a-b/6 must be divisible by 6
sorry
sorry
ik
its of the form 32+60n
set n=0
yeah
then it's 1
then it's 92
92 mod6 = 2
so answer is 2
if n can't be 0
solve for a-b
plug n = 1
boom done
did they ask for least remainder?
okay
its just 32+60n mod6
whish is just 32mod6
or is it
yes it is
which is 2.
@whole scaffold they asked the minimum value of 32 + 60n mod6
basically for any n it 6 always divides 60n
right?
so we are left with 32
now what's the remainder of dividing 32 by 6?
that's your answer
then it's 2.
I'll re write it
a-b=6b+2-12n
Divide by 6
You dont need to add and subtract 6n
I dont see why you would do that
$a=6b+7$
$\
\$
$b=12n+5$ multiply both sides by 5
$\
\$
$\rightarrow 5b = 60n + 25$
i own a thinking banana
i own a thinking banana
$a-b - 5b=7$
i own a thinking banana
$a-b=7+5b$
i own a thinking banana
$a-b=7 + 60n+25$
i own a thinking banana
$a-b=32+60n$
i own a thinking banana
now for any $n$ 6 always divides $60n$
Yeah this is better
i own a thinking banana
leaving only $32$ for us to divide
i own a thinking banana
So remainder for 32 by 6
Now what remainder does $32$ produce being divided by $6$?
i own a thinking banana
,w 32mod6
,w 6457nıd7
btw mod is basically like a belt
Wolfram Alpha doesn't understand your query!
Perhaps try rephrasing your question?

,w 6457mod7
Nid
that's remainder of 6457 dividing 7
now do the questions in #maths-riddles
they are good for practice
We plug and chug
When you give me multiple choice yeah
u guys r rlly dedicated
fr
Give problems
is that an m
You posted it in the riddle channel asking others to solve it
i can help u with geoemtry
damn
what is the test for
@whole scaffold did i give u the right answer for q10?
oh
nice
