Algebra.Com's Answer #796187 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "When you post a problem, take the time to ask the question you have. In this case, it is obvious what the question is... but it shouldn't be our responsibility to determine what the question is; YOU should ask it. \n" ); document.write( "------------------------------------------------------------ \n" ); document.write( "If you are going to use formal algebra to solve the problem, make your work a lot easier than what is shown by the other tutor by using a single variable. \n" ); document.write( "Since the number of cats is 5 more than the number of dogs... \n" ); document.write( "let d = number of dogs \n" ); document.write( "then d+5 = number of cats \n" ); document.write( "The total number of animals is 125: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "ANSWER: 60 dogs and 65 cats. \n" ); document.write( "You can do exactly the same calculations to get the answer informally, without formal algebra: \n" ); document.write( "(1) Count the 5 \"extra\" cats and set them aside. \n" ); document.write( "(2) That leaves equal numbers of cats and dogs, with the total number of animals now 125-5 = 120. \n" ); document.write( "(3) So the remaining animals are 120/2 = 60 each of cats and dogs. \n" ); document.write( "(4) Now bring back those 5 \"extra\" cats to see that there are 60 dogs and 60+5=65 cats. \n" ); document.write( " \n" ); document.write( " |
