An airplane is flying at 35,000 feet above sea level. The airplane starts to descend a a rate of 2,500 feet per minute. Let m be the number of minutes. Write an expression to describe the height of the airplane after x amount of minutes.

15 batches are the most you can make

step-by-step explanation:

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

hope this is what you were asking for!
