Question

If (4x^2-3x^2):(2x^2+5x^2)=12:19 then x:y is

Answer 1

(4 x^2 - 3 x^2 ) : ( 2 y^2 + 5 y^2 ) = 12 /19

x ^2 : 7 y^2 = 12 / 19

x^2 / 7 y^2 = 12 / 19

x^2 / y^2 =( 7 × 12 ) / 19

( x / y )^2 = 84 / 19

x / y = √ ( 84 /19 )

x / y = 9.1 / 4.3

x : y = 9.1 : 4.3

x : y = 9 : 4 ( approximate )
