Over twenty years, it was found that the number of doctors of medicine, md (in thousands), in the united states can be approximated by md=(28,390+693t)/(85-t) where t=0 represents 1980. the number of doctors of osteopathy, do (in thousands), can be approximated by do=(776-12t)/(65-2t) . write an expression for the total number i of doctors of medicine (md) and doctors of osteopathy (do). simplify the result. how many mds did the united states have in 2010? how many mds did the united states have in 2010?

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
