Answer:
D. 104
Step-by-step explanation:
We know that xy and yz are supplementary to each other
That means they add up to 180
We can set up an equation with this information
(4x+32)+(2x+40)=180
6x+72=180
6x=108
x=18
Now that we know what x is, we can plug it into 4x+32 to find degree of xy
4(18)+32
72+32

To identify the dependent variable in the testable, look out for the variable that is affected by the other. The variable that changes as a result of another variable is the dependent variable.
In a research study, there are typically two main variables that direct the scientific enquiry. They are:
- Dependent Variable, and
- Independent Variable
The independent variable causes a change in the dependent variable, i.e. the dependent variable receives the <em>effect</em>, the independent variable is the <em>cause </em>of the change.
It is very easy to identify the dependent variable in any testable hypothesis once you are able to pick out which variable is causing a change in the other.
For example, let's say the topic of a research is: <em>The Impact of Sunlight on Germination Rate of Seedlings.</em>
Here, <em>Sunlight </em>is the independent variable affecting <em>Germination Rate</em>.
The dependent variable here would be: <u><em>Germination Rate.</em></u>
Therefore, to identify the dependent variable in the testable, look out for the variable that is affected by the other. The variable that changes as a result of another variable is the dependent variable.

Step-by-step explanation:
70:100 (They're related because 7 x 10 = 70 and 10 x 10 = 100)
14:20 (They're related because 7 x 2 = 14 and 10 x 2 = 20)
