I think it should be x<=5/6 1. multiply thru by 5.... 2x-15x+10>=5x-5 2. combine like terms... -13x+10>=5x-5 3. get your variables on one side(-5x from both sides) -18x+10>= -5 4. isolate the variable... (-10..) -18x>=-15 5. /both sides by -18 !!careful!! whenev...

It's a proportion...53/63=x/67 in other words... st.height/st.shadow=tr.height/tr.shadow Solve by cross multiplying...63x=53*67 so x=56.37inches.. Good Luck!
