**Answer:**

To calculate final grade we use the formula:

Final grade = H( the weight of h) + Q( the weight of q) + P (the weight of project) +T (the weight of test) + F(the weight of final exams).

This formula help us to calculate the grade we need to get.

**Step-by-step explanation:**

Solution:

Suppose grade breakdown for certain college course is as follow:

Homework = 15%

Quizzes = 20%

Project = 10%

Test = 40%

Final exam= 15%

Let G represent the final grade

H represents homework average,

Q represents quizzes and P represent project, T represent test average and F represent final exam.

To calculate final grade we use the formula:

Final grade = H( the weight of h) + Q( the weight of q) + P (the weight of project) +T (the weight of test) + F(the weight of final exams).

This formula help us to calculate the grade we need to get.

The correct representation o**f 6 + 2n > 12 (n > 3)** is **(3, ∞) a**nd a number line with an **open circle** at **+3** and being shaded from **+3 to +5**.

<h3>What is an

**equation**?</h3>

An equation is an **expression** that shows the** relationship **between two or more numbers and variables.

Given the equation::

6 + 2n > 12

Subtracting 6 from both sides:

6 + 2n - 6 > 12 - 6

**2n > 6**

Dividing by 2:

**n > 3**

The correct representation o**f 6 + 2n > 12 (n > 3)** is **(3, ∞) a**nd a number line with an **open circle** at **+3** and being shaded from **+3 to +5**.
