Tom is making a punch that contains 80% cranberry juice and the rest ginger ale. The punch has 2 liters of ginger ale. Part A: Write an equation using one variable that can be used to find the total number of liters of cranberry juice and ginger ale in the punch. Define the variable used in the equation and solve the equation. Hint: 0.8x represents the number of liters of cranberry juice in the punch. (5 points) Part B: How many liters of cranberry juice are present in the punch? Show your work.
Answers
Answer:
There are 8 liters of cranberry juice in the punch
Step-by-step explanation:
Part A
We know that of the punch, 80% is cranberry juice.
Let's call Z the amount of cranberry juice and Y is the amount of ginger ale.
Let's call X the amount of Ponche
The amount of punch is equal to the amount of cranberry juice plus the amount of ginger ale
(i)
Then we know that:
(ii)
We also know that:
liters (iii)
Part B.
Now we can solve the equation:
Replace (ii) and (iii) in (i)
X = 10 liters.
Now we substitute X = 10 in equation (ii) and find the amount of Cranberry juice.
Z = 8 liters.
There are 8 liters of cranberry juice in the punch

Answer:
The constant of proportionality for the group of boxes is 25.
Step-by-step explanation:
Given : The volume of a box(V) varies directly with its length(l). If one of the boxes has a volume of 325 cubic inches and a length of 13 inches.
To find : What is the constant of proportionality for the group of boxes?
Solution :
The volume of a box(V) varies directly with its length(l).
Using k for the constant of proportionality.
We can express the relationship between V and l
If V varies directly with l.
V = kl
According to question,
If one of the boxes has a volume of 325 cubic inches and a length of 13 inches, then
Therefore, The constant of proportionality for the group of boxes is 25.

The value of y intercept in the given equation of line is -6 or (0,-6) .
Given,
Equation of line :
2x + 5y = −30
Now,
y intercept is when the line crosses the y axis or when x = 0
Substitute x = 0 in the equation of line to get the y intercept value .
So,
2(0)+5y=-30
0+5y=-30
5y=-30
divide 5
y=-6
Thus,
value of y intercept is -6 or (0,-6)
