Algebra.Com's Answer #765903 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "1. None of them. \n" ); document.write( "\"10 times greater than x\" means x, plus x 10 more times -- i.e., 11x. The place values of the 5's in the given numbers are either 5, 50, or 500; none of those numbers is 11 times another of them. \n" ); document.write( "If you mean \"10 times AS GREAT\", then again the place values are either 5, 50, or 500. Find one pair where the values of the two 5s are 5 and 50, or 50 and 500. \n" ); document.write( "2. The value of the \"7\" in 270 is 7*10 = 70. The value of the \"7\" in 207 is 7*1 = 7. 70 is 9 times greater than 7. (70 = 7+63 = 7 + 9 times 7, so 9 times GREATER THAN 7). 70 is clearly 10 TIMES AS GREAT AS 7; it's not 10 times GREATER THAN 7. \n" ); document.write( " |
