Algebra.Com's Answer #3829 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Let x = the deceased man's fortune.\r \n" ); document.write( "\n" ); document.write( "To his wife, he leaves (1/2)x \n" ); document.write( "To his son, he leaves (1/7) of (1/2)x \n" ); document.write( "To his butler, he leaves (2/3) of ((1/7) of (1/2)x) \n" ); document.write( "To his pig, he leaves the remaining $2,000.00\r \n" ); document.write( "\n" ); document.write( "All these amounts should add up to $x, the deceased man's fortune.\r \n" ); document.write( "\n" ); document.write( "(1/2)x + (1/7)(1/2)x + (2/3)(1/7)(1/2)x + $2,000.00 = $x Simplify and solve for x. Factor an x from the first three terms.\r \n" ); document.write( "\n" ); document.write( "x(1/2 + 1/14 + 2/42) + $2,000.00 = $x Add up the fractions. The common denominator is 42.\r \n" ); document.write( "\n" ); document.write( "x(21/42 + 3/42 + 2/42) + $2,000.00 = $x \n" ); document.write( "x(26/42) + $2,000.00 = $x Simplify the fraction. \n" ); document.write( "x(13/21) + $2,000.00 = $x Subtract x(13/21) from both sides. \n" ); document.write( "$2,000.00 = $x - x(13/21) \n" ); document.write( "$2,000.00 = $x(8/21) Multiply both sides by the multiplicative inverse of 8/21 \n" ); document.write( "$2,000.00(21/8) = $x \n" ); document.write( "$x = $5,250.00 The deceased man's fortune. \n" ); document.write( " \n" ); document.write( " |
