1) Two numbers are in the ratio of 3:5. If 8 is subtracted from their sum, the result is 40.
\n" ); document.write( " What is the larger number?
\n" ); document.write( "Let x = the multiplier
\n" ); document.write( "then
\n" ); document.write( "3x = the smaller number
\n" ); document.write( "5x = the larger
\n" ); document.write( "\"If 8 is subtracted from their sum, the result is 40.\"
\n" ); document.write( "5x + 3x - 8 = 40
\n" ); document.write( "8x = 40 + 8
\n" ); document.write( "8x = 48
\n" ); document.write( "x = 48/8
\n" ); document.write( "x = 6 is the multiplier
\n" ); document.write( "therefore
\n" ); document.write( "6(5) = 30 is the larger number
\n" ); document.write( "and
\n" ); document.write( "6(3) = 18 is the smaller, check this in the given statement
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "2)The ratio of two complementary angles is 2:7. What are the measures of the two angles?
\n" ); document.write( "let x = the multiplier
\n" ); document.write( "2x + 7x = 90
\n" ); document.write( "9x = 90
\n" ); document.write( "x = 10 is the multiplier
\n" ); document.write( "then
\n" ); document.write( "20 and 70 are the two angles
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "3) Two angles are supplementary. The larger angles is 3 less than twice the smaller angle. Find the measure of the larger angle.
\n" ); document.write( "let a = the larger angle
\n" ); document.write( "let b = the smaller
\n" ); document.write( "a = 2b-3
\n" ); document.write( ":
\n" ); document.write( "a + b = 180
\n" ); document.write( "2b-3 + b = 180
\n" ); document.write( "3b - 3 = 180
\n" ); document.write( "3b = 180 + 3
\n" ); document.write( "3b = 138
\n" ); document.write( "b = 183/3
\n" ); document.write( "b = 61
\n" ); document.write( "Find a
\n" ); document.write( "a = 2(61) - 3
\n" ); document.write( "a = 122 - 3
\n" ); document.write( "a = 119 degrees is the larger angle
\n" ); document.write( ":
\n" ); document.write( "Check this 119 + 61 = 180
\n" ); document.write( "
\n" ); document.write( "
\n" );
