Agroup of students recycles 7 2/3 pounds of glass and 9 3/4 pounds of paper. how many pounds of paper and glass did the kids recycle all together?

17 5/12 lb total

Step-by-step explanation:

Find the total weight of the materials recycled:

7 2/3 lb + 9 3/4 lb

Here the LCD is 12.  (Both 3 and 4 divide evenly into 12.)

Rewriting 7 2/3 lb + 9 3/4 lb with the LCD 12, we get:

7 8/12 lb + 9 9/12 lb, or 16 17/12 lb.

The fraction here must be reduced.  We get

17 5/12 lb total      (Recognize that 17/12 = 1 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.
