Text exerciseThe Mars rover Spirit landed on January 3, 2004. Just over 1 yr later, on January 14, 2005, the Huygens probe landed on Titan (one of Saturn’s moons). At their closest approach, the distance from the Earth to Saturn is 29 million mi more than 21 times the distance from the Earth to Mars. If the distance to Saturn is 743 million mi, what is the distance to Mars? Can somebody give me an answer? I have few answers but I want to be sure. I understand equations and etc. but when it comes to text exercises I don't understand them...Does it mean I'm not for math? |

Re: Text exerciseQuote:
The distance to Mars is (743 - 29)/21 = 34 million miles. Do you see how I got the expression on the left-hand side of that equation? |

Re: Text exerciseThank you for the answer. I hope someday I'll do math like you :) Could you help with the last one? Find three consecutive even integers where the sum of triple the first and twice the second is eight more than four times the third. The English is the second my language. I know English well, but I need to get used to this kind of exercises. In my language there are no good books about math. |

Re: Text exerciseHere's a start: 3a + 2(a + 2) = 4(a + 4) + 8. Do you see I arrived at that? What is your first language? |

Re: Text exerciseMy first language is Lithuanian. Well I'll need to try harder to learn math, I hope I'll learn it someday :) And thank you for your answer. Very helpful forum. |

Re: Text exerciseYou're welcome. Good luck with your studies. (your English seems pretty good, by the way). |

Re: Text exerciseWhat about "Twice the second is eight more" what about 8 ? |

Re: Text exercise3a + 2(a + 2) = 4(a + 4) + 8 |
