Question

plz give me answer on paper and send me plz plz plz OK

Answer 1

• ( 3 x + 2 y ):( 2 x + 5 y )

    Put the value of x and y .

      = ( 3 x 2 + 2 x 3) : ( 2 x 2 + 5 x 3 )

      = 12 : 19

       = 12 : 19

Answer 2

Given: x : y = 2 : 3

Given equation : ( 3 x  + 2 y ) : ( 2x + 5y )

         Solution : -

$\implies \dfrac{3x+2y}{2x+5y}$

Divide both sides by "y"

$\implies \dfrac{\bigg( 3 \times \dfrac{x}{y} \bigg) + \bigg( 2 \times \dfrac{y}{y} \bigg)}{ \bigg( 2 \times \dfrac{x}{y} \bigg) + \bigg( 5 \times \dfrac{y}{y}\bigg)}$

Now, substitute the value of $\dfrac{x}{y}$ which is $\dfrac{2}{3}$

$\implies \dfrac{\bigg( 3 \times \dfrac{2}{3} \bigg) + \bigg( 2 \times 1 \bigg)}{ \bigg( 2 \times \dfrac{2}{3} \bigg) + \bigg( 5 \times 1 \bigg)}\\\\\\\implies \dfrac{( 1 \times 2 ) + 2 }{ \dfrac{4}{3} + 5 }\\\\\\\implies \dfrac{2 + 2}{\dfrac{4+15}{3}}\\\\\\\implies \dfrac{4}{\dfrac{19}{3}} \\\\\\\implies \dfrac{12}{19}$

Therefore the value of ( 3x + 2y ) : ( 2x + 5y ) is 12 : 19.
