Answer:

Area of land: 800 miles.

Step-by-step explanation:

Since the map is a square, you can assume that all 4 sides will equal 8 inches. (Giving you a perimeter of 32, and an area of 64.) Since each inch corresponds to 5 miles, you multiply 8 by 5 which equals 40.

Algebra I

Solving systems of equations using substitution/elimination
Solving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

y = x + 1

y = 1/2x + 3

Step 2: Solve for x

Substitute in y: x + 1 = 1/2x + 3
Subtract 1/2x on both sides: 1/2x + 1 = 3
Subtract 1 on both sides: 1/2x = 2
Divide both sides by 1/2: x = 4

Step 3: Solve for y

Define original equation: y = x + 1
Substitute in x: y = 4 + 1
Add: y = 5

Step 4: Graph

We can confirm our answer.
