Step-by-step explanation:
I think answer A should be the correct answer
Answer: 
Step-by-step explanation:
Given the equation:

You must solve for "x" to find its value.
You can follow these steps:
- Add
to both sides of the equation:


- Subtract 9 from both sides of the equation:

- Divide both sides of the equation by 8. Then you get:

Let
d = the total number of dairy cattle
b = the total number of beef cattle
2/3 of the dairy cattle on a farm are in the barn, and we know that 24 dairy cattle are in the barn thus:
(2/3)d = 24
d = 36 dairy cattle
1/4 of the beef cattle are in the barn and there are 16 beef cattle in the barn thus:
(1/4)b = 16
b = 64 beef cattle
64 - 36 = 28
There are 28 more beef cattle on the farm than dairy cattle.
To calculate the area of the black material on the flag, we need the shape and the dimensions of the black material itself.
<em>Since the question is incomplete, as the dimension of the flag and the dimension of the black material are not given, I will provide a general explanation</em>
<em />
Assume the shape of the black material is a rectangle.
The area will be calculated as:

Take for instance;

The area is:


Assume the shape of the black material is a square.
The area will be calculated as:

Take for instance;

The area is:


Assume the shape of the black material is a triangle
The area will be calculated as:

Take for instance;

The area is:


So, in general.
You need to first get the shape of the black segment on the flag, then calculate the area using the appropriate formula.
