Answer:

The correct answer is option 2

Subtract 6.4 from the each side of equation

Step-by-step explanation:

The given equation,

3.5n  + 6.4 = 42.5

To solve the equation

3.5n  + 6.4 = 42.5

Step 1: Subtract 6.4 from the both side

3.5n  + 6.4 - 6.4 = 42.5 - 6.4

3.5n = 36.1

Step 2:  Divide both side by 3.5

3.5n/3.5 = 36.1/3.5

n = 10.34

Therefore the correct answer is option 2

Hello there, and thank you for posting your question here on brainly.

Short answer: 280 miles.

Why?

You can find this out by finding out how much 1 in is by dividing 200 by 5. (200 / 5 ==> 40) So 1 in = 40 miles. Now, we multiply that by 7, so we can find out how much 7 in would be. (7 * 4 ==> 280) 7 inches on the map represents 280 miles.

Hope this helped you! ♥
