You can put this solution on YOUR website!
let the next test have score of x then average means you add them all up, divide by 3 and that equals the average
\n" ); document.write( "\"%2883%2B92%2Bx%29%2F3=90\" solve for x, multiply both sides by 3 to get rid of the fraction
\n" ); document.write( "83+92+x=270
\n" ); document.write( "175+x=270 subtract 175 from each side
\n" ); document.write( "x=95
\n" ); document.write( "
\n" );
