Katherine is visiting patients in a hospital. She visits 18 patients in 6 hours. At that rate, how many patients will she visit in 9 hours?

Let's find the unit rate first, I like to order my units:

= = , so 3 patients per hour is the

-unit rate.

Now let's order them to equal x(unknown patients)/9(hours)

 =   = 27 patients per 9 hours. So your answer

is 27 patients.

27 patients

Step-by-step explanation:

18patients = 6 hours

18/6 = 3

each hour for 6 hours she attends to 3 patient

6 hours + 3 hours make up 9 hours

since for each hour she attended to three patients we would say

1 hr = 3 patients

1 hr = 3 patients

1 hr = 3 patients

Total: 3 hrs = 9 patients

18 patients + 9 patients = 27 patients

so for 9 hrs Katherine will visit 27 patients.

Thank you

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.

there still no table
