Question

19-x при x= 17 ;-17;8,5;- 4,9;30,2

Answer 1

19-17=2
19-(-17)=36
19-8=11
19-5=14
19-(-4,9)=23,9
19-30,2=-11,2

Answer 2

19- 17= 2
19 -( -17)= 19+17=36
19 - 8,5= 10,5
19 -( -4,9)= 19+4,9=23,9
19- 30,2= - 11,2

Answer 3

To find the value of the expression 19 - x for different values of x, let's substitute the given values and calculate the results:

1. When x = 17: 19 - 17 = 2

2. When x = -17: 19 - (-17) = 19 + 17 = 36

3. When x = 8.5: 19 - 8.5 = 10.5

4. When x = -4.9: 19 - (-4.9) = 19 + 4.9 = 23.9

5. When x = 30.2: 19 - 30.2 = -11.2

Therefore, the results are:

• For x = 17, the result is 2.
• For x = -17, the result is 36.
• For x = 8.5, the result is 10.5.
• For x = -4.9, the result is 23.9.
• For x = 30.2, the result is -11.2.
