Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

Evaluate the expressions inside the parentheses:

    - 11 - 2 = 9

Replace the expressions with their values:

    - (8(9) - 5(9))/3

Multiply the numbers:

    - 72 - 45 = 27

Divide by 3:

    - 27/3 = 9

So, the correct answer is: 9

*************

The second migration to Habshah took place in 616 A.D

The group of emigrants' second  migrations time comprised 83 men and 18 to 19 women

Explanation

The price of 10 chairs = The price of 4 tables

Concept:

Linear equation of two variable = A equation is said to be linear equation in two variable if it is written in the form of ax + by + c = 0 Where, x and y are variables and a, b, and c are the integers

Calculation:

Let us assume the cost price of a chair be X and cost price of a table be Y

⇒ According to the question

⇒ 10X = 4Y ----(1)

⇒ 15X + 2Y = 4000 ----(2)

⇒ By equation (1) and (2)

⇒ 15X + 5X = 4000

⇒ X = 200 and Y = 500

⇒ The price of 12 chairs and 3 tables = (12 × 200) + (500 × 3) = 2400 + 1500 = 3900

∴ The required result will be 3900.

Explanation

To find the average (arithmetic mean) of a and b, we need to first solve for a and b.

Given equation: 10a + 10b = 35

Divide both sides by 10: a + b = 3.5

Since we want to find the average of a and b, we can use the fact that the average of two numbers is equal to their sum divided by 2.

So, (a + b)/2 = 3.5/2

= 1.75

Therefore, the average (arithmetic mean) of a and b is 1.75.
