\"The upper Angel Falls, the highest waterfall on Earth, are 750 m higher than Niagara Falls.\"
\n" ); document.write( "Let x = height of Niagara Falls, then (x+750) = height of Angel falls
\n" ); document.write( ":
\n" ); document.write( "\"If each of the falls were 7m lower, the upper Angel Falls would be 16 times as high as Niagara Falls.\"
\n" ); document.write( "16(x-7) = (x+750) - 7
\n" ); document.write( "16x - 112 = x + 743
\n" ); document.write( "16x - x = 743 + 112
\n" ); document.write( "15x = 855
\n" ); document.write( "x = 855/15
\n" ); document.write( "x = 57
\n" ); document.write( ":
\n" ); document.write( "How high is each waterfall?
\n" ); document.write( "Niagara height = 57 ft
\n" ); document.write( "Angels height = 750 + 57 = 807 ft
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution using this statement:
\n" ); document.write( ":If each of the falls were 7m lower, the upper Angel Falls would be 16 times as high as Niagara Falls.\"
\n" ); document.write( " 807 - 7 = 16(57 -7)
\n" ); document.write( "800 = 16(50)
