Answer 1

я думаю

8+Х=8х(рис) зробила таня

8Х-8=Х

 

Answer 2

Expression with Variable x and its Set of Values

To answer your question, let's first define the expression with the variable x. We know that Ira made 8 drawings, and Tanya made x times fewer drawings than Ira. Therefore, the expression can be written as:

Tanya's Drawings = Ira's Drawings - x

Now, let's determine the set of values that x can take. Since Tanya made x times fewer drawings than Ira, x must be a positive integer. The maximum value of x would be 7, as Tanya cannot make more drawings than Ira. Therefore, the set of values that x can take is:

x ∈ {1, 2, 3, 4, 5, 6, 7}.

Difference in the Number of Drawings

To find out how many more drawings Ira made compared to Tanya, we need to substitute the values of x into the expression and calculate the difference.

Let's calculate the difference for each value of x:

- For x = 1: Tanya's Drawings = 8 - 1 = 7 - For x = 2: Tanya's Drawings = 8 - 2 = 6 - For x = 3: Tanya's Drawings = 8 - 3 = 5 - For x = 4: Tanya's Drawings = 8 - 4 = 4 - For x = 5: Tanya's Drawings = 8 - 5 = 3 - For x = 6: Tanya's Drawings = 8 - 6 = 2 - For x = 7: Tanya's Drawings = 8 - 7 = 1

Therefore, the difference in the number of drawings Ira made compared to Tanya is:

7, 6, 5, 4, 3, 2, 1.
