Algebra.Com's Answer #62137 by tutor_paul(519)![]() ![]() You can put this solution on YOUR website! If you consider her first 3 tests, you can write the following equation, where x,y, and z are her test scores: \n" ); document.write( " \n" ); document.write( "Equation #1: \n" ); document.write( "Now, after she takes her 4th test to achieve the 94 average, (call that score 'w'), you can write: \n" ); document.write( "Equation #2: \n" ); document.write( "Now, substitute the value of (x+y+z) from Equation #1 into Equation #2: \n" ); document.write( " \n" ); document.write( "And solve for w... \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Good Luck, \n" ); document.write( "tutor_paul@yahoo.com \n" ); document.write( " |
