The value of y is 2 when x = 6 if the relationship between x and y is y = (1/3)x because x and y vary directly.
<h3>What is a proportional relationship?</h3>
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that:
x and y vary directly
y ∝ x
y = kx
Plug y = 3 and
x = 9 in the above equation to get the value of k:
3 = 9k
k = 3/9 = 1/3
y = (1/3)x
Plug x = 6
y = (1/3)6
y = 2
Thus, the value of y is 2 when x = 6 if the relationship between x and y is y = (1/3)x because x and y vary directly.

Answer:
226
Step-by-step explanation:
To find the percentage of a given value, firstly convert to a decimal by dividing by 100:
82 ÷ 100 = 0.82
Now, multiply this decimal by the number of tickets:
275 x 0.82 = 225.5
Because you can't sell half a ticket, round up.
This means the total of tickets they need to sell is 226.
Hope this helps!
Answer:
1/2c-4
Step-by-step explanation:
First, you distribute the fraction on the outside to the numbers inside of the parenthesis. So, you distribute 1/2 to c, which gives you 1/2 x c = 1/2c. Then, you distribute the 1/2 to -8, which gives you 1/2 x -8 = -4. You combine these expression together and get your final answer as 1/2c-4.
