And an 11 ounce bag of rice noodles makes 10 servings at that rate find how many ounces of noodles I needed for 19 servings to the nearest ounce how many ounces of noodles are needed for 19 servings

20.9 ounces of rice noodles are required to make 19 servings.                    

Step-by-step explanation:

We are given the following in the question:

11 ounce bag = 10 servings

Ration of ounces of rice noodles to servings is:

We have to find ounces of noodles are needed for 19 servings.

Thus, we can write:

Thus, 20.9 ounces of rice noodles are required to make 19 servings.

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
