❓ Help EXPERT SA MATHEMATICS TRANSLATION

[Erzie]

Hello mga ka PHC patulong naman ako neto Math translation , yung mga magagaling jan namag translate patulong po hehe


Ps yung pangalawang pic po is example

ay sorry may mali, edited ko na..hahah

Correct me if I'm wrong, but I think number 7 should be:

7. let x = hundreds digit; y = tens digit; z = ones digit
N = 100x + 10y + z
X = y/2 ; y = 2z ; z=z

N = 100x + 10y + z
N = 100(y/2) + 10(2z) + z

Kung per separate digit lang talaga yung hihingin, pwede yung [(c+2)/2][c+2][c].
Pero hinahanap kasi three-digit number. So technically, dapat sum siya ng product of each digit sa place value nila.

Ahhh ganun pala yun nalilito ako

 

[kuromomochi]

Ahhh ganun pala yun nalilito ako

Baka di ka nakinig sa teacher mo nung tinuro yan

 

[SpectaculairE]

Baka di ka nakinig sa teacher mo nung tinuro yan

Nako, tinuro yata yan noong absent ako eh

in my opinion, problem #7 is a defective problem or should i say incomplete . . . una, hindi puwedeng maging odd number & 8 ang ones/unit digit . . . ikalawa, tens digit should not be an odd number & 0 . . . at ikatlo, hundreds digit should not be 0,8 & 6 and should not be an odd number except 3 . . .

in short, the only possible answers are:
120
242
364
486

***note that a "digit" is any whole number from 0-9

hehe... good idea po pero kasi nakalagay "a three digit number"which means isang buong three didit number lng sya. Kumbaga singular sya dahil sa word na "a". Pero kung wala yong word na "a" talagang sum sya ng three numbers.

 

[kalawagon]

pero i suggest na gawin itry mo muna bago ka humingi ng tulong.

Roster set to rule set sir .. Yan ba yan sir

Yun nga po. "A three digit number" yung nakalagay. So dapat ang sagot na lalabas is "a number with three digits".
What I was saying is SUM of the PRODUCT of EACH DIGIT on their corresponding PLACE VALUE, not sum of the three numbers. Kasi if we were to put yung mathematical E×ρréššion into actual computation, ganto lalabas na sagot:

Let c = 2
=[(c+2)/2][c+2][c]
=[(2+2)/2][2+2][2]
=[2][4][2]
=16

If using my equation:

Let x = hundreds digit; y = tens digit; z = ones digit

Let z = 2
X = y/2 ; y = 2z ; z=z

= 100x + 10y + z
= 100(y/2) + 10(2z) + z
= 100(2z/2) + 10(2z) + z
= 100 [(2)(2)/2] + 10(2)(2) + 2
= 200 + 40 + 2
= 242

Hence, this E×ρréššion is correct.

*note: sa abstract algebra di lahat ng parenthesis or other symbol meaning multiplication. I use [ ] only to separate the digits.

I get your point on this one, but this is not acceptable for the mathematical E×ρréššion required in question #7.
You cannot use the square bracket symbol merely just to separate the digits. Pwede yan, yes, for abstract algebra. But even in abstract algebra, square brackets are mostly used to define elements in a set, and you still need to use comma in between.
Given that the requirement is a mathematical E×ρréššion, answer must be an E×ρréššion that can be evaluated into something.
Using your E×ρréššion for #7 is hindi pwede, because applying this into calculation, lalabas na imumultiply sila. Based on his assignment, sa tingin ko naman hindi to abstract algebra.

Let's just stick to the basics.

makikisabat ako ha hehe . . . yung values sa equation mo dapat sinimplify mo pa na instead x=y/2, y=2z, z=z
bakit hindi na lang x=z, y=2z, z=z para "z" na lang ang common variable nila atsaka nga pala dapat y=2+z at hindi y=2z

pero mali pa rin ang equation mo dahil subukan mong magsubstitute ng any single digit number dyan except 2 . . . mali ang kalalabasan niyan

Uy I missed that out. Thanks sa correction. Value of y must be z+2 nga.

I think tama yung sinabi mong defective yung question. I tried to substitute the numbers pero di lahat nagcocomply. Baka need niya to i-raise sa teacher niya. Hahaha!

Also, di ko na sinimplify kasi baka malito si ts. Nagset naman ako ng conditions, up to him kung gusto niya isimplify yung E×ρréššion. And if iseset ko ng x=z, di masasatisfy yung condition na "hundreds digit is half the tens digit". Baka hanapin nung teacher.

Senpai, ikaw na !

HAHAHAHAHAHA miss you all! SpectaculairE skysolstice xdmeruchan wala na si kuehado senpai huhuhu di ko matag

 

[skysolstice]

HAHAHAHAHAHA miss you all! SpectaculairE skysolstice xdmeruchan wala na si kuehado senpai huhuhu di ko matag

Anong kaguluhan to

 

[kuromomochi]

Anong kaguluhan to

Di ko rin alam eh. Basta alam ko graduate na ako eh. Bakit ba ako nagsasagot ng assignment ng iba.

 

[xdmeruchan]

HAHAHAHAHAHA miss you all! SpectaculairE skysolstice xdmeruchan wala na si kuehado senpai huhuhu di ko matag

Wala ko dyan, wala kong kasalanan, inosente ako!

 

[kalawagon]

also should I say may kulang talaga or may mali sa question? kasi di mo nmn talaga makukuha ang exact value ng kung anong hundreds digit ang gagamitin mo, kung 100 ba, 200, 300 or etc.... Its more on assumptions.

that is why I used abstract algebra...hehe

 

[kuromomochi]

Huhuhu ang hirap na mag-isip ng mababaw kapag masyadong advance na napag-aralan.

 

[zaitsev]

i think the problem is defective . . . even in the board exams, there are defective problems and so, considered as bonus/es . . . kaya dapat bonus na ng prof ni ts to

True! Hahahaha kahit sa board exam kahit pwede mo isagot E, wag mong isasagot.
