3. He started out with 36 cards and then added 372 more. So now he has a total of 408 cards. He has 5 folders each with the same number of cards. 408 divided by 5 = 45 with three left over.
Using the proportional relationship between X and Y ; the completed table is :
- X ____ Y
- 2 ____ 1.5
- 3 ____ 2.25
- 3 ____ 4
Let :
x = Serving of chicken
y = ounces of noodles
The proportional relationship :
x = ky ; k = constant of proportionality
x = 2 ; y = 1.5
2 = 1.5k
k = (2 ÷ 1.5)
k = 1.333
The expression for the relationship is :
x = 1.333y
When x = 3 ; y =?
3 = 1.333y
y = 3/1.3333
y = 2.25
When y = 3
x = 1.333(3)
x = 4
Therefore, the complete table is :
X ____ Y
2 ____ 1.5
3 ____ 2.25
3 ____ 4

Answer:
First option: 
Step-by-step explanation:
<h3>
The complete exercise is: "The height of a hill, h(x), in a painting can be written as a function of x, the distance from the left side of the painting. Both h(x) and x are measured in inches 
. What is the height of the hill in the painting 3 inches from the left side of the picture?</h3>
You have the following function provided in the exercise:
You know that 
represents the height of the hill (in inches) and "x" represents the distance from the left side of the painting (in inches)
Knowing that you can determine that, if the painting 3 inches from the left side of the picture, the value of "x" is the following:
Therefore, you need to find the value of when in order to solve this exercise.
So, the next step is to substitute into the function:
And finally, you must evaluate in order to find 
.
You get that this is:
139 = x + (2x + 10)
139 = 3x + 10
129 = 3x
/3 /3
43 = x
Therefore
