Basic Algebra

Thumbs up to the 'algebraic' prowess of these guys.

I observed some regular guys that get high on snake meat, bum and bust matters and APC/PDP deceptions are not making any comments... Why so?

A girl went to school and the teacher asked, how old are you? She replied I don't know but I know that I'm half my mother's age.

The teacher asked OK how old is your mother? She said I don't know but I know that my dad is 5 years older than my mother.

The teacher, then asked how old is your dad? She said I don't know but I know that if we add our ages the answer is 100 years...

Now, how old is the girl, her mum, and her dad?

Please show your workings!

That one concern the teacher, the girl n her parents

Everything na magic to my face sha. I just hate maths

CodeTemplar:
No o ... I just dey form e-professor oh.

some please knw book sha

This is also another approach

oh, maths.
Whats is the secret?

Let me give you another approach by taking it from the back this time


Let the father's age be = P
Mother's age = P-5 since the father is 5 years older than her
and daughters age = (P-5)/2 since her age is half of the mum's.
(P-5)/2 + (P-5) + P = 100
(P-5) + 2(P-5) + 2P = 200
P-5 + 2P-10 +2P =200
5P= 200 + 15
5P= 215
P=215/5
P= 43
Father = 43 years old
Mother= 43- 5(since the father is 5 years older)= 38 years old.
Daughter= 38/2 (since her age is half of the mum's)= 19 years old.
(F,M,D)= (43,38,19) is the required set of solution.

Wetin concern agboro with overload

nobody fit give me heart attack bfre going to bed. But I must confess thumb up to those who made attempt.

awon mathematicians

Mutemenot:
This thread won't excel cos many Nairalander go japa at the sight of maths

This how me n my fellow bad mathematicians look d thread

God bless u for putting smile on my face bfre bed time

U won't see all this Feminist here now o,

If na to help man equalise akara now they ll make FTC..

TourismMan:
People like us even when you don solve the maths finish give us make we copy, we still dey make mistakes untop. Lol.

Your dullness na follow come be dat lol.

Bizmagnet:

Let mother's age be x, then the girl's age will be x/2 being the half of her mother's.
Since the father's age is 5 years greater than the mother's, his age will be x+5.
According to the girl, the sum of their ages is 100. Therefore,
girl's age (x/2 years)+ mother's age(x years) + father's age((x+5)years) = 100.
Now, x/2 + x + x+5= 100
2x + x/2 = 100-5
2x + x/2 = 95
4x + x = 190
5x = 190
x = 190/5
x= 38.
Therefore, the mother is 38 years old, the girl is 19 years old and her dad is 43 years old.

guy, I can't solve maths the way you did. Well done.

That’s what I thought too ...

Ok

Baba, I hail thee

Justice has been done to the given problem, thumbs up to the critical thinkers in the house.

The foundation of mathematics!!! If u didn't excel In this during your primaries, Just forget about mathematics!!! Same thing with Verbal reasoning!!!

All the ladies her claim they don't like maths. But if it's money they will love.

I just don't know mathematics I tire

Let's assume the mother's age is x
Daughter's age =1/2x
Father's age = 5+x
The sum of the father, mother and daughter's age = 100
Therefore, 5+x+1/2x+x=100
2.5x=100-5
X= 95/2.5 =38

Therefore, the mothers age is 38
Daughter's age is 38/2 = 19
Father's age is 38+5 = 43

oloriLFC:
All those above calculations dey do my eyes somehow. Mathematics isn't just my thing, don't know why?

What then is ur tin?

Pls stop solving sir
We don get the hansa

This is also another approach

This is the most interesting working so far.
Guy u go good for dy dx

Franko Franko, well don o
You give men work finish naim u discharge abi

Basic Algebra

Na so.
After dem don help u find d ansa finish

bestgift4ever:
Pls I need a Maths and Account teacher for real

Contact me for maths only,
That's what I do.

masterpiecer:


Na so.
After dem don help u find d ansa finish

That is too basic my jss2 will solve it
You solve this
X^(logx3) =10000x^3

The first time I see mathematics on niaraland front page. U most be a friend to a mod.
Any which way.
I need more maths

Let Nina's age be denoted with x, her mum's denoted with y and her dad's z

From the questions,

y= 2x....... Equation 1
y + 5 = z...... Equation 2
x+ y +z = 100 ..... Eqn 3

Substituting eqn 1 into eqn 2 for y

2x + 5 = z..... Eqn 4

Substituting for eqn 4 into eqn 3 for z

x + 2x +2x + 5 = 100

Adding items with x

5x + 5 = 100

Subtracting 5 from both sides,

5x = 100 - 5

5x = 95

Divide both sides by 5

x = 95/5

x = 19

Substituting 19 for x in eqn 1

y = 2(19)

y = 38


Substituting for x and y in eqn 3

19 + 38 + z = 100

57 + z = 100

Subtract 57 from both sides

z = 100-57

z = 43

Recal that x denotes Nina's age, y her mum's and z her dad's.

Therefore,

Nina is 19

Her mum is 38

Her Dad 43

Math and physics. Best subjects ever! And, of course ,English.

Offpoint:
Dull people like us wey dey dey back seat when we see math question on board we....do the below picture

God bear me witness I don't know what the hell those guys above are writing, small thing dem don carry X enter the matter...

but the girl na idiot sha

the reasons I still have my money in the bank is because there's no X in banks

so u are my friend, i hate that thing like..... Hmm, well maybe if there is another life after this, i will like to know it, but not in this current life, i don't know anything that look like mathematics, poor me.
