margaret is twice as old as jenny, and sarah is twice as old as margaret. Their combined ages total 133 years. How old is each person? in equation form
\n" ); document.write( "Let Jenny's age be: x
\n" ); document.write( "Then Margaret's age is: 2x
\n" ); document.write( "Then Sarah's age is: 2(2x)=4x
\n" ); document.write( "They add up to be: 133
\n" ); document.write( ":
\n" ); document.write( "x+2x+4x=133
\n" ); document.write( "7x=133
\n" ); document.write( "7x/7=133/7
\n" ); document.write( "x=19
\n" ); document.write( ":
\n" ); document.write( "Jenny's age: x=19
\n" ); document.write( "Margaret's age: 2x=2(19)=38
\n" ); document.write( "Sarah's age:4x=4(19)=76
