Respuesta :

by addition the value is 2.

Red pebble is equal to 3 yellow pebble

A blue marble is equal to a red pebble and 2 yellow pebble

A green pebble is equal to 3 red pebble

Suppose R,B,Y,G represents red, blue, yellow, and green pebbles

R=3Y

B=R+2Y

G=3R

Express Red in terms of yellow in blue pebble equation

B=3Y+2Y =5Y

Now, express Green Pebble in terms of yellow pebble

G=3R=3(3Y)=9Y

by addition Value of:

[tex]\frac{G+B}{2R+Y} \\\frac{9Y+5Y}{2*3Y+Y} \\\frac{14Y}{7Y} =2[/tex]
