the perimeter of an isosceles triangle is p=2a+b. find the numerical value of a if p=10and b=3.
\n" ); document.write( ".
\n" ); document.write( "Plug in what was given into:
\n" ); document.write( "p=2a+b
\n" ); document.write( "to get:
\n" ); document.write( "10=2a+3
\n" ); document.write( "subtracting 3 from both sides:
\n" ); document.write( "10-3=2a+3-3
\n" ); document.write( "7=2a
\n" ); document.write( "divide both sides by 2:
\n" ); document.write( "7/2 = (2a)/2
\n" ); document.write( "7/2 = a
\n" ); document.write( "or
\n" ); document.write( "3.5 = a\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
