Algebra.Com's Answer #369264 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Let N be the unknown number. \n" ); document.write( ". \n" ); document.write( "\"Increased by 2 thirds of the number\" means find 2 thirds of N and add it to (or increase) N by it. \n" ); document.write( ". \n" ); document.write( "So we have N and increase it by 2 thirds N, and this translates to: \n" ); document.write( ". \n" ); document.write( "N + (2/3)N \n" ); document.write( ". \n" ); document.write( "According to the problem, this equals 35. So we have an equation: \n" ); document.write( ". \n" ); document.write( "N + (2/3)N = 35 \n" ); document.write( ". \n" ); document.write( "We can get rid of the denominator 3 by multiplying both sides (all terms) by 3 and we then have: \n" ); document.write( ". \n" ); document.write( "3N + 2N = 105 \n" ); document.write( ". \n" ); document.write( "Adding together both terms on the left side reduces the equation to: \n" ); document.write( ". \n" ); document.write( "5N = 105 \n" ); document.write( ". \n" ); document.write( "Solve for N by dividing both sides of this equation by 5 to get: \n" ); document.write( ". \n" ); document.write( "N = 105/5 = 21 \n" ); document.write( ". \n" ); document.write( "That's the answer. The number is 21. 1 third of 21 is 7 so 2 thirds of 21 is 14. When you increase the number (21) by 2 thirds of 21 it is: \n" ); document.write( ". \n" ); document.write( "21 + 14\r \n" ); document.write( "\n" ); document.write( "and this equals 35, just as the problem says it should. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand this problem and how you can solve it. \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( " |
