13 3/4 + x = 7 1/4
x = 7 1/4 - 13 3/4
x = 29/4 - 55/4
x = 26/4
x = 6 2/4
x = 6 1/2

The correct answer is A
{
}
<u>EXPLANATION</u>

This implies that

We solve the compound inequality to obtain,

Remember that, dividing through by negative 1 reverses the inequality sign
The solution set is
{
}
The area of sector is 1.57 m²
<u>Explanation:</u>
Given:
Radius, r = 3 m
Central angle of a sector = 1/9π radians
Area of sector, A = ?
We know:
Area of sector, A = 
where,
α is the central angle in radians
On substituting the value we get:

Therefore, the area of sector is 1.57 m²
The ordered pair that represents a maximum is (5,189)
