For this case we have that initially the bottle contains 
of liter of water.
If a person drinks 
of the contents of the bottle we have:
Thus, the person drinks 
liters of water.
Answer:
The person drinks liters of water.
D
Step-by-step explanation:
The number of guests is the independent variable and should be between 1 and 50. We can use a scale of 10's
The cost is the dependent variable and the minimum cost is 100 and should rise from there
The scale would be from 100 's
Answer:
Thus, the value of x = -36 when y = 15
Step-by-step explanation:
We know that if y varies directly with x, we can express the relationship such as
y ∝ x
y = kx
k = y/x
where 'k' is called constant of variation.
Given
y = -5
x = 12
Using the equation
k = y/x = -5/12
Thus, the value of k = -5/12
Finding x when y = 15
y = 15
k = -5/12
substituting y = 15 and k = -5/12 in the equation
y = kx
15 = -5/12 (x)
15×12 = -5x
180 = -5x
divding both sides by -5
-5x/-5 = 180/-5
x = -36
Thus, the value of x = -36 when y = 15
Answer:
Equation B
Step-by-step explanation:
Equation B because:
it is 7x + 3
so for the first one, it's 7 + 3
the second one is 14 + 3
the third one is 21 + 3
the fourth one is 28 + 3
