Write an expression/equation for what it says:
\n" ); document.write( ":
\n" ); document.write( "Ana is 24 years older than twice the age of her younger sister.
\n" ); document.write( "A = 2S + 24
\n" ); document.write( ":
\n" ); document.write( " In ten years, their ages:
\n" ); document.write( "(A + 10)
\n" ); document.write( "and
\n" ); document.write( "(S+10)
\n" ); document.write( ":
\n" ); document.write( "In 10 years their combined ages will be 110 years.
\n" ); document.write( "(A+10) + (S+10) = 110
\n" ); document.write( "A + 10 = 110 - S - 10
\n" ); document.write( "A = 110 - S - 10 - 10
\n" ); document.write( "A = 90 - S
\n" ); document.write( ":
\n" ); document.write( "(How old are they now?
\n" ); document.write( "From the 1st equation, substitute (2S+24)for A in the above equation:
\n" ); document.write( "2S + 24 = 90 - S
\n" ); document.write( "2s + S = 90 - 24
\n" ); document.write( "3s = 66
\n" ); document.write( "S = 66/3
\n" ); document.write( "S = 22 yrs is the sisters age
\n" ); document.write( ":
\n" ); document.write( "A = 2S + 24
\n" ); document.write( "A = 2(22) + 24
\n" ); document.write( "A = 44 + 24
\n" ); document.write( "A = 68 yrs is Ana's age
\n" ); document.write( ":
\n" ); document.write( "Check solution using the statement:
\n" ); document.write( "\"In ten years, their combined ages will be 110 years\"
\n" ); document.write( "(68 + 10) + (22 + 10) = 110
\n" ); document.write( ":
\n" ); document.write( "Could follow this OK? Any questions? \n" ); document.write( "
\n" );
