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.

Answer:
504 km
Step-by-step explanation:
divide 180 by 15 (because 3 hours is 180 minutes)
after you divide you get 12
then multiply 12 by the 42 kilometers and you get 504
Think of dividing by 2 splitting it in half, if you round it you get about 1500 then split that in half. it would be around 750.
The answer is the last option
Answer:
x =-2
Step-by-step explanation:
5x+1=2x-5
Subtract 2x from each side
5x-2x+1=2x-2x-5
3x+1 = -5
Subtract 1 from each side
3x+1-1 = -5-1
3x=-6
Divide by 3
3x/3 = -6/3
x = -2
