Question 570387: I am not sure if this under the right category but here is the question..
The Mars Rover Spirit landed on Jan 3, 2004. Just over one year later on Jan 14 2005 the huygens probe landed on Titan. At the closest approach the distance from Earth to Saturn is 29 million miles more than 21 times the distance from Earth to mars. If the distance to Saturn is 743 million miles, what is the distance to mars?

All we need are these words:

the distance from Earth to Saturn is 29 million miles more than 21 times the distance from Earth to mars. If the distance to Saturn is 743 million miles, what is the distance to mars

Let x = the distance from Earth to Mars (in millions of miles)

the distance from Earth to Saturn is 29 million miles more than 21 times the distance from Earth to mars.

Replace the words "the distance from Earth to Saturn" by 743

743 is 29 million miles more than 21 times the distance from Earth to mars.

Replace the words "the distance from Earth to Mars" by x

743 is 29 million miles more than 21 times x.

Replace the words "21 times x" by 21x

743 is 29 million miles more than 21x.

Erase the "million miles", because that's understood

743 is 29 more than 21x.

Replace the words "29 more than 21x" with 21x + 29

743 is 21x + 29

Replace the word "is" by an equal sign "=":

743 = 21x + 29

Subtract 29 from both sides:

714 = 21x

Divide both sides by 21

34 = x

Answer: It's 34 million miles from Earth to Mars.
