Abegi,wat tim 2mao

Richiez: 1. If r = 5 z then 15 z = 3 y, then r =
(A) y
(B) 2 y
(C) 5 y
(D) 10 y

r = 5z
z= r/5
15z = 3y becomes
15 (r/5) = 3y
therefore
3r = 3y
r=y ans A

yea...or dividin 15z=3y by 3..dats r=5z=y,.b3 low

aysuccess99: can't wait for the solution and the final score board. @kendzyma,guy u are hot o, u dey parra gan....best of luck dude.....welldone to all participants of this quiz, u guys are really hot here o...good job my co-ordinators@richiez,doubledx,alphamaximus......keep the flag flying high#thumbs up#

my guy,na u o..abegi no wine me..

U dn receiv am?@doublex

Done!

doubleDx: ==========================
Solution to Question 4
==========================

First, we have to know the value(s) of Q before knowing which of the expression given is true..

√(Q + 5) = (Q - 1)
Simply square both sides to remove the square root, yielding=>
{√(Q + 5)}² = (Q - 1)²
Q + 5 = (Q - 1)(Q - 1)
Expanding the RHS yields=>
Q + 5 = (Q - 1)(Q - 1)
Q + 5 = Q² - 2Q + 1
Collecting like terms =>
Q² - 3Q - 4 = 0
Factorizing the above quadratic expression yields =>
Q² - 4Q + Q - 4 = 0
:. Q(Q - 4) + 1 (Q - 4) = 0
Thus=> Q - 4 = 0 0r Q + 1 = 0
Hence=> Q = 4 OR Q = -1

For statement 1, 2Q = -2 is true since one of the values of Q is (-1) and 2Q => 2(-1) = -2.
For statement 2, Q² = 1 is also true, since one of the values of Q is (-1) and Q² => (-1)² = 1
For statement 3, 4Q = 16 is also true, since Q is also equal to 4, and 4Q => 4(4) = 16

Thus statements 1, 2, 3 are all true;

Hence, the solution => Option C. 1, 2 & 3. is the correct answer.


Note:

To Check your answer for Q = (-1),

Substitute for Q = -1 =>

√(Q + 5) = (Q - 1)

±√(-1 + 5) = (-1 - 1)

±√4 = -2

±2 = -2

Since square root is ±; hence, satisfying the equation!

Option D was a trap for careless mathematicians

Richiez: There is Going to be a make-up test question. I have received requests from many people who still wants to participate.
Here goes the make-up test question (application of mathematics)

The relationship between temperature in degrees celcius (^oC) and degrees Fahreinheit (^oF) is;

^oC = 5/9 (^oF - 32)

at what temperature will ^oC be equal to ^oF ?

Just post the correct answer, no workings!
Deadline is 4pm.
When this time elapses, another quiz master Doubledx will post the correct answer and the names of those who got the correct answer.
