6m-3m^2. You can only add,subtract, multiply, and divide the same variables. The only same variables are 2m and 4m so you add them, that's how you get 6m. -3m^2 is a different variable so you leave it alone. <span />

A map has a scale of 1/8 of an inch is equal to 1/4 of a mile. What is the unit rate of inches per mile
algol [13]

Answer:

1 inch per 2 miles.

Step-by-step explanation:

1/8 of an inch = 1/4 of a mile.

To solve the rate of inch per mile, multiply 8 to both sides (to make inch = 1)

(1/8)(8) = 1

(1/4)(8) = 8/4 = 2

The unit rate of inches per mile is 1 inch per 2 miles.
