If 6 staplers weigh 13 ounces how much do 7 staplers weigh? Give answer as mixed number.

15

Step-by-step explanation:

Set up a proportional relationship equation and solve how much 7 staplers weighs.

   solve by cross product

6x = 91

x = 91/6  

Now  convert 91/6  to a mixed number.

6 will go into 91  , 15 times remainder  1  so as a mixed fraction will be  15

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.
