Algebra.Com's Answer #106214 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! If John gives Haiz $7, they will have the same amount of money. If Haiz gives John $7, the ratio of the amount of money he has to the ratio of the money John has will be 1:2. How much money has each of them at first? \n" ); document.write( ": \n" ); document.write( "Let the original amts be; J and H \n" ); document.write( ": \n" ); document.write( "Write an equation for the two statements, \n" ); document.write( ": \n" ); document.write( "\"If John gives Haiz $7, they will have the same amount of money.\" \n" ); document.write( "J - 7 = H + 7 \n" ); document.write( "J = H + 7 + 7 \n" ); document.write( "J = H + 14 \n" ); document.write( ": \n" ); document.write( "\" If Haiz gives John $7, the ratio of the amount of money he has to the ratio of the money John has will be 1:2.\" \n" ); document.write( " \n" ); document.write( "Cross multiply: \n" ); document.write( "J+7 = 2(H-7) \n" ); document.write( "J+7 = 2H - 14 \n" ); document.write( "J = 2H - 14 - 7 \n" ); document.write( "J = 2H - 21 \n" ); document.write( ": \n" ); document.write( "Substitute (H+14) for J \n" ); document.write( "H + 14 = 2H - 21 \n" ); document.write( "14 + 21 = 2H - H \n" ); document.write( "H = $35 \n" ); document.write( ": \n" ); document.write( "From the 1st equation \n" ); document.write( "J = 35 + 14 \n" ); document.write( "J = $49 \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check solution in both statements: \n" ); document.write( "\"If John gives Haiz $7, they will have the same amount of money.\" \n" ); document.write( "49 - 7 = 35 + 7 \n" ); document.write( ": \n" ); document.write( " If Haiz gives John $7, the ratio of the amount of money he has to the ratio of the money John has will be 1:2. \n" ); document.write( "35 - 7 = 28 \n" ); document.write( "49 + 7 = 56 \n" ); document.write( " \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
