The 2 in the equation d=2c means that the price (dollars) is equal to 2 cupcakes
1. I don’t know exactly what you need but 4 divided by 7 is about 0.57 feet or 6.86 inches
2. If you are allowed excess, then you will have 7 pieces each at 0.5 feet with half a foot left extra
Answer:
y=1/2x +5
Step-by-step explanation:
This is because when you look at the graph the points would go up 1 and to the right 2 for the next coordinate like (6, 8) and (8, 9). When you divide 4 by 2 you get 2 and when added to 5 you get the output 7. This can be said again for the output of 10.
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
