Answer:

Step-by-step explanation:
We are asked to solve the given equation:
.
To solve this equation we will combine like terms by moving all the terms containing x to the left hand side of equation and terms without x to right hand side of equation.
Let us add 8x to both sides of our equation.



Let us subtract 8 from both sides of our equation.


Upon dividing both sides of our equation by 6 we will get,



Therefore, the value of x equals 1 will satisfy our given equation.
Answer:
<h2>The area of the total figure is around 535.43 square centimeters.</h2>
Step-by-step explanation:
In the image attached, you can notice that all rectangles have a base of 20 centimeters.
Also, each side of the equilaterals triangles is 8 centimeters.
Notice that the height of each rectangle is equal to a side of a triangle.
Using all given vales, the area of each rectangle is

The area of all rectangles is
, because there are three rectangles in total.
The area of each triangle is

The area of both triangles is

Now, the area of the whole figure is the sum of the area of triangles and rectangles

Therefore, the area of the total figure is around 535.43 square centimeters.
Let Base fee be X and No. of Miles be Y.
According to the question
Total Charge= (X+ 88Y)
251.55=20.99+ 0.88Y
Y= 251.55-20.99/0.88
Y= 262 miles
