If 1 inch is .25 miles then all you have to do is multiply .25 miles by 5 inches and u get 1.25 miles.
N= 2
Substitute 2 in for n in expression
=(5 + n) ÷ (n - 1)
=(5 + 2) ÷ (2 - 1)
=7 ÷ 1
=7
If n= 2, the expression equals 7.
Hope this helps! :)

General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
(6x² - 4x + 2) - (-2x² + 3x - 5)
<u>Step 2: Simplify</u>
- Distribute negative: 6x² - 4x + 2 + 2x² - 3x + 5
- Combine like terms (x²): 8x² - 4x + 2 - 3x + 5
- Combine like terms (x): 8x² - 7x + 2 + 5
- Combine like terms (Z): 8x² - 7x + 7
I know this doesn't really help but... Good luck on the test!! And also I'm pretty sure they have youtube vids on how to do this stuff. Well, anyway bye!!! Good luck!!!
