Question

1)19-x при x=17; -17 ; 8,5; -4/9; 30,2

Answer 1

19-17=2
19-(17)=36
19-8.5=10.5
19-(-4/5)=19 целых 4/5
19-30.2=-10.8

Answer 2

To find the value of the expression $19 - x$ for different values of $x$, simply substitute each value of $x$ into the expression and perform the calculation:

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 $x = -\frac{4}{9}$: $19 - \left(-\frac{4}{9}\right) = 19 + \frac{4}{9} = \frac{171}{9} + \frac{4}{9} = \frac{175}{9}$

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