Diana has 3/4 foot of ribbon. She used 1/3 foot to make a bow for her doll. How much ribbon, in feet, is left over?

5/12

Step-by-step explanation: you first need to make the denominators of the fractions equivalent. The least common factor of 3 and 4 is 12. 3/4 becomes 9/12 and 1/3 becomes 4/12. Now you can subtract. 9/12 - 4/12 = 5/12

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.
