If 2 inches equal 40 miles, 4 inches would equal 80. You don’t have to do anything else because you can eliminate all the other answers. The only one it could be is B. 82.5 miles.
x = 13
subtract x from both sides of the equation
6 = 2x - x - 7
6 = x - 7
add 7 to both sides
6 + 7 = x ⇒ x = 13
As a check
substitute this value into the equation and if both sides are equal then it is the solution
left side = 13 + 6 = 19
right side = (2 × 13) - 7 = 26 - 7 = 19
hence x = 13 is the solution

Step-by-step explanation:
<u>Step 1: Determine the area of the left rectangle</u>
We can tell that the total shape seems like two rectangles glued together. We can separate the left rectangle and determine the area of it and then determine the area of the right rectangle and combine them. Lets first solve the left rectangle.



<u>Step 2: Determine the area of the right rectangle</u>



<u>Step 3: Determine the total area</u>
