\n" ); document.write( "1. Mike is 20 cm shorter than Tim
\n" ); document.write( "2. Jane is 25 cm taller than Tim
\n" ); document.write( "3. Jill is 21 cm shorter than Jack
\n" ); document.write( "4. Tom is 38 cm taller than Mike
\n" ); document.write( "5. Jake is 36 cm shorter than Mark
\n" ); document.write( "6. Mark is 8 cm taller than Jane
\n" ); document.write( "7. Jill is 11 cm shorter than Jake
\n" ); document.write( "8. Tom is 183 cm tall\r
\n" ); document.write( "\n" ); document.write( "How tall is Jack?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let Tim’s height be T
\n" ); document.write( "Then Mike’s is: T – 20 cm\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let Jack’s be J
\n" ); document.write( "Then Jill’s is: J - 21 cm\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Jane’s is: T + 25 cm
\n" ); document.write( "Tom’s is: T – 20 + 38, or T + 18 cm\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let Mark’s height be M
\n" ); document.write( "Then Jake’s is: M – 36 cm
\n" ); document.write( "Also, M = T + 25 + 8, or M = T + 33 cm
\n" ); document.write( "J – 21 = M – 36 – 11, or M = J – 21 + 47, or M = J + 26 cm\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since Tom is 183 cm tall, then T + 18 = 183 ---- T, or Tim is 183 – 18, or 165 cm
\n" ); document.write( "Since M = T + 33, and M = J + 26, then: T + 33 = J + 26
\n" ); document.write( "165 + 33 = J + 26 ------ Substituting 165 for T
\n" ); document.write( "J, or Jack’s height = 198 – 26, or \"highlight_green%28172%29\" cm \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can do the check!!\r
