The car was towed for 48 miles.
Step-by-step explanation:
Given,
Amount charges by Acme towing = $30
Per mile charges = $3
Total charged = $174
Let, x be the number of miles.
Towing charges + Per mile charges*number of miles = Total charged
30+3x=174
Subtracting 30 from both sides
Dividing both sides by 3
The car was towed for 48 miles.

The general term is
(a sub n; n is a subscript)
The first term is a1
The second term is a2
The third term is a3
and so on...
The first term starts at n = 1. We replace the n in
with 1 to get
. A similar thing happens with n = 2 and onward
The domain is therefore the set {1, 2, 3, 4, 5, ...} which is the set of...
* Counting numbers
* Positive Whole numbers
* Natural numbers
Those are three ways to express the same set
We can also say
where n is an integer or whole number
A similar inequality would be
which is effectively the same as idea as the last inequality (n is also an integer or whole number).
Answer:
1. 
2. 
Step-by-step explanation:
1. The area of a hexagon is A = 
Here our a is 4, so plugging in 4 to our equation gives 
which simplifies to
2. The area of an octagon is 
Here our r is 9, so plugging in 9 to our equation gives 
which simplifies to
It is choice A. Supplementary angles are angles that add up to 180. This means that the angle you are looking for will be 180-57, which equals 123.
