Independent variable is the variable you change.
Dependent variable is the variable you measure that results/depends on the independent variable.
Since u is the independent variable, you need to set the equation equal to w by isolating/getting the variable "w' by itself in the equation:
[This is because u is the variable you change, and w is the variable you measure that depends on the independent variable(u)]
4u + 8w = -3u + 2w Subtract 2w on both sides to get "w" on one side of the equation
4u + 6w = -3u Subtract 4u on both sides
6w = -7u Divide 6 on both sides to get "w" by itself

Answer : The fraction empty container is,
Step-by-step explanation :
As we are given that:
The capacity of container = 60 mL
In the given figure, the container is filled with 25 mL.
That means,
60 - 25 = 35 mL container is empty.
Now we have to calculate the fraction of it is empty.
The fraction of it is empty =
The fraction of it is empty =
The fraction of it is empty =
Therefore, the fraction empty container is,
Answer:
Step-by-step explanation:
Given
m cups of water = p cups of rice
Required
Cups of water required for p + 2 cups of rice
<em>The question shows a direct proportion between cups of rice and cups of water.</em>
<em>So, the first step is to get the proportionality constant (k)</em>
<em />
This is calculated using the following expression;
Where k represents cups of water and p represents cups of rice
Make k the subject of formula
Let x represents cups of water when cups of rice becomes p + 2;
k becomes:
Equate both expressions of k; to give
Multiply both sides by p + 2
<em>Hence, the expression that represents the cups of water needed is </em><em></em>
