In a math book we use blank ink with white pages. Thus, it is a math test.
Given information:
Black and white and has lots of problems.
As per given in question, A test is prepared to check the knowledge obtained by a person during the study time. It was performed before the test presentation. Well, a math book can have black ink with white pages but also a math test can have black and white combination.
It is said to be full of problems because it is made to solve exercises on different topics. And it is said to be black and white because normally the sheets are white and the ink is black.
Therefore, it is a math test.

Answer:
The answer is: A math test
Step-by-step explanation:
A test is designed to assess the knowledge obtained by a person during the study time that was performed before the test presentation.
It is said to be full of problems because it is made to solve exercises on different topics.
And it is said to be black and white because normally the sheets are white and the ink is black.
2/3*x=1
Find the number which is x
2/3x=1
Multiply both sides by 3/2 to get x by itself
2/3x(3/2)=1(3/2)
Cross out 2 and 3. Divide by 2 and 3. Then becomes 1*1*1*1*x=x
x=1(3/2)
pretend that there is a denominator for 1 which is 1
x=1/1(3/2)
Multiply the numerators together
1*3=3
Multiply the denominators together
1*2=2
Answer:
x=3/2
To find the number, solve the equation: 7.2x - 8 = -29.6
To solve this problem, let's represent the unknown number as 'x'. The equation can be written as 7.2x - 8 = -29.6.
To isolate 'x', we can add 8 to both sides of the equation: 7.2x = -21.6.
Then, divide both sides of the equation by 7.2 to solve for 'x': x = -3.

Answer:
The square of the scale
Step-by-step explanation:
Scaling
Suppose we know the scale of the distances, for example, r=5. It means that for each centimeter in the drawing, it corresponds to 5 cm in the real object being scaled. If we wanted to find the ratio of the areas, we would need to scale both dimensions and the ratio would be the square of the scale factor. In our example, the ratio of the areas would be 25, i.e. each square centimeter would correspond to 25 square centimeters
The rule for finding the ratio of the areas of two objects: The square of the scale
To solve this problem, you add all the numbers together and divide by the total amount of things. In this case, there are six scores, 210, 195, 213, 201, 226, and 155. You would add all of these things together, and then divide by six. All of these things added together equals 1,200. This divided by 6 is 200. David's average score would be a. 200. Hope this helps!
