Algebra.Com's Answer #78464 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Let x represent the first odd integer. The second consecutive odd integer must be 2 units \n" ); document.write( "above the first. Therefore, the second odd integer is x + 2. And the third odd integer is \n" ); document.write( "2 units above the second. So it is at x + 2 + 2 = x + 4. In summary, the three consecutive \n" ); document.write( "odd integers are x, x + 2, and x + 4. \n" ); document.write( ". \n" ); document.write( "If you add these together, the problem tells you that their sum is 201. In equation \n" ); document.write( "form this is: \n" ); document.write( ". \n" ); document.write( "x + x + 2 + x + 4 = 201 \n" ); document.write( ". \n" ); document.write( "When you collect like terms the left side becomes: \n" ); document.write( ". \n" ); document.write( "(x + x + x) + (2 + 4) = 201 \n" ); document.write( ". \n" ); document.write( "This simplifies to: \n" ); document.write( ". \n" ); document.write( "3x + 6 = 201 \n" ); document.write( ". \n" ); document.write( "Get rid of the 6 on the left side by subtracting 6 from both sides of the equation. \n" ); document.write( "This subtraction results in the equation becoming: \n" ); document.write( ". \n" ); document.write( "3x = 195 \n" ); document.write( ". \n" ); document.write( "Solve for x by dividing both sides by 3 to get: \n" ); document.write( ". \n" ); document.write( "x = 195/3 = 65 \n" ); document.write( ". \n" ); document.write( "So the first odd integer is 65. Therefore the three consecutive odd integers are 65, 67, and 69. \n" ); document.write( ". \n" ); document.write( "Check: does the sum of these three consecutive odd integers = 201? Yes, 65 + 67 + 69 does \n" ); document.write( "equal 201. Therefore, our answer is correct. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand the problem. \n" ); document.write( ". \n" ); document.write( " |
