note: f=fruit
y=yoghurt
2:3
f : y
f/y=2/3
=> 3*f=2*y
f=(2*y)/3
we know that f+y=185g
(2*y)/3+y=185g
(2*y+3*y)/3=185g
5*y/3=185
y=(185*3)/5
y=111g
=>the mass of the yoghurt is 111 g
Answer:
11/6
Step-by-step explanation:

As a mixed number, this is 1 5/6.
I don't know where you got those answers, but the actual equation that represents those points is: y = -1/2x + 11. None of those listed above are correct.
Answer:
x + y = 100
5x + 2y = 35
