An airplane at 30,100 feet above the ground into sending at the rate of 2150 feet per minute. Write and solve a linear equation
Art [367]

Answer:

30,100 - 2150m = 0 m = 14

Step-by-step explanation:

First, the linear equation to find how long it will take would be 30,100 - 2150m , with m being the number of minutes it took. m = 14, because 2150 × 14 equals 30,100, and 30,100 - 30,100 equals 0.
