are you trying to solve for x?

Answer 2

this is the problem
A plane travels from Orlando to Denver and back again. On the five-hour trip from Orlando to Denver, the plane has a tailwind of 40 miles per hour. On the return trip from Denver to Orlando, the plane faces a headwind of 40 miles per hour. This trip takes six hours. What is the speed of the airplane in still air?

Answer 3

thats a multiplication sign

Answer 4

oh okay, let me try to work it out!

Answer 5

according to your equation a= 440

Answer 6

if my formula right?

Answer 7

am suposed to be solving for speed of the airplane in air...

Answer 8

yes it looks right

Answer 9

it should be

Answer 10

in your formula the a stands for the speed in the dead air

Answer 11

ok

Answer 12

a standts for air distance yes.

Answer 13

a stans for the rate
r*t = D

Answer 14

5(a+40) is the distance of the way there
4(a-40) is the distance of the way back
you make them equal, because the distance there and back are the same

Answer 15

Astrid is correct a = 440
Planes go fast...

Answer 16

can you please explain how you solved the equation?

Answer 17

start by simpilfying each side of = , distribute
5(a+40) = 4(a - 40)
5a + 200 = 4(a - 40)

Answer 18

then distb the other side
5a + 200 = 6(a - 40)
5a + 200 = 6a - 240 sorry I wrote the wrong number before

Answer 19

4a-160

Answer 20

4*40=160

Answer 21

look at the original equation....I typed in the 2nd side wrong
the 4 was supposed to be a 6 sorry

Answer 22

oh yeah your right :

Answer 23

5(a+40) = 6(a - 40)
5a + 200 = 6a - 240)

Answer 24

now how do you get eh a by itself?

Answer 25

hint do the opposte operations

Answer 26

add a's ?

Answer 27

which one do you want to get rid of...cant have an a on both sides
(usually I pick the smaller one)

Answer 28

how do you get rid of 5a?

Answer 29

I add 240 and 200 thats 440 but what do I do with a?

Answer 30

dont know :(

Answer 31

what is the opp of 5a? -5a
subtract 5a on both sides

Answer 32

1r=440 ?

Answer 33

right...right....right!

Answer 34

so that is my final answer right??....:)

Answer 35

5a + 200 = 6a - 240
-5a -5a
200 = a - 240
+240 +240
440 = a

Answer 36

yep , well miles per hour...
