Explanation

A consistent system of linear equations has at least one solution.

If there is exactly one solution, the system is independent.

If there are infinitely many solutions, the system is dependent.

Explanation

The age of Sohail, Afzal and Bilal are 17,16 and 12 respectively. If the age of Aslam also included the average of the ages is increased by 5. What is the age of Aslam?

Average = 17 + 16 + 12/3

                = 15 yrs

Given if Aslam added to them, their average increases by 5

=> Average of 4 members 15+5 = 20

What is the age of Aslam

20x4 = 80

15x3= 45

80-45 = 35

 Hence, the age of Aslam is 35 yrs.

Explanation:

We can write 10% as 10/100

Simplifying the fraction 10/100, we get 1/10 which is equal to decimal number 0.1

Thus, 10% as a decimal form is given as 0.1

Explanation

Simplify the square root:

√1.96/100

√1.96/ √100

√1.96 = 1.4

√100 =10

14/10 = 0.14

Explanation

1 meter = 100 centimeters.

1 centimeter = 10 millimeters.

Therefore, 1 meter = 100 × 10 = 1000 millimeters.
