Best ResponseYou've already chosen the best response.0I wrote two equations relating the masses of apples (a), bananas (b) and plums (p). 3 a + 1b = 10p 1a + 6p = 1b Can you solve this system of equations?

Best ResponseYou've already chosen the best response.0(or solve for a relationship between mass of the bananas and plums) (aka number of plums (mass) = number of bananas (mass) )

Best ResponseYou've already chosen the best response.1Here is why: From first relationship given you can write 10 plums  3 apples = 1 banana From the second relationship you can write when multiplying the equation by 3: 3 apples + 18 plums = 3banana. Now writing them to see how they look 3 apples + 18 Plums =3 banana 3 apples +10 Plums = 1 banana Now add these two equations  28 Plums = 4banana divide thru by 4 7 Plums = 1 banana
