Danny poured 78 liters of water into x, y,and z. the ratio of the volume of water in container x to the volume of water in container y is 5: 2. the ratio of the volume of water in container y to the volume of water in container z is 8: 11. how much water was poured in container x? how much more water was poured into container x than container z?

x+y+z = 78

x/y = 5/2

y/z = 8/11

(x,y,z) = (40,16,22)

x-z = 18

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
