In this question,

the student converted all the mixed numbers to improper fractions; followed by finding a common denominator of all the terms (resulting 120).

Is this step necessary?

In this round of 6 am quiz, you will attempt to uncover the mystery behind Fido's Mind-Reading ability.

**Fido claims that he can read our mind.**

**Click at the following link to test him out!!! :**

**http://www.digicc.com/fido/**

**There are several ways to explain Fido's trick, u****sing mathematical reasoning. **
*Make an attempt to use ALGEBRA to explain the "trick"?*

Enter your thinking (algorithm) in Comments.

The total length of 4 roads is (3x - 1) km.

What are the possible lengths of the 4 roads in kilometres?

Enter your suggested lengths in comments.

What are the possible lengths of the 4 roads in kilometres?

e.g. The length of the 4 roads are: **x km, x km, x-7 km, 6 km**

Check: **x + x + (x - 7) + 6 = 3x - 1 **

Enter your suggested lengths in comments.

The perimeter of a rectangle is (6x + 5y) cm.

Enter your suggested dimensions in Comments

Suggest 2 possible dimensions of the rectangle.

e.g.

Length of rectangle = 2x + 2y cm

Breadth of rectangle = x + 0.5y cm

Check:

Perimeter = 2 (2x + 2y) + 2 (x + 0.5y) cm

= 4x + 4y + 2x + y cm

= 6x + 5y cm

This question is compulsory.

Jane did the following:

*Enter your response in Comments. *

**3a + b = 3ab****2s + 4t = 6st**

Do you think Jane is correct in her algebraic manipulations?

If yes, please write down examples to show that her answer is correct.

If not, explain to Jane her mistakes and help her to correct.

The following are

**3***x***5 - 2***y**p*+ 2*q*- 45**mn**

**2***x*= 4*x*+ 8 = 20*x*² = 36**2***x*+*y*= 4

In the following algebraic expressions:

(a) 6

*x*is a variable- 6 is the coefficient of
*x* - There is no constant

*y*is a variable- 2 is the coefficient of
*y* - 5 is the constant

*m*and*n*are variables- 3 and 7 are coefficients of
*m*and*n*respectively - 9 is the constant

*p*and*q*are variables- 1 and 2 are coefficients of
*p*and*q*respectively - -45 is the constant

*a*and*b*are variables- 5 and -3 are coefficients of
*a*and*b*respectively - 1 is the constant

*x*and*y*are variables- 1 and -1 are coefficients of
*x*and*y*respectively - There is no constant
