Marty ate 4/6 of his pizza and luis ate 5/6 of his pizza. marty ate more pizza than luis . how is that possible?

Marty's pizza most likely was larger.  

Step-by-step explanation:

I'll give an example

5/6 of 9 is 7.5 while 4/6 of 12 is 8

i'm not sure i quite understand, could you provide more information?

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
