The algebraic expression of the part A is 6+7x. And the verbal expression for 3*(n+8) is "the triple of the sum between the numbers n and 8".
<h3>
Linear Expression</h3>
A linear expression can be represented by a line. The standard form for this equation is: y=ax+b , for example, y=2x+7.
First, you should choose a variable for unknow number. Here, the variable will be x. Then, 7 times a number can be represented for 7x.
The word <em>more </em>will be represented for the add symbol (+). Thus,
the algebraic expression is 6+7x.
The expression 3*(n+8) can be represented for the sentence:
The triple of the sum between the numbers n and 8.

In a short answer, to find average you need to add it all up and divide by the number of things you added. Ex. say I want to find the average for my english class, my grades are 90, 98, 100, 87, and 70. I would start by adding them up to get 445. then since i have 5 grades, i would divide the sum 445 by 5 and get an 89 as my average.
(Everything in this answer is example only, not my real grades.)
