15,5-0,5 x , x=-8 ...........................................​

Answer 1

Ответ:

15,5-0,5*(-8)=

15,5+4=19,5

Answer 2

To evaluate the expression 15.5 - 0.5x when x = -8, we substitute -8 in place of x and perform the calculation.

So, plugging in x = -8, we have:

15.5 - 0.5(-8)

= 15.5 + 4

= 19.5

Therefore, when x = -8, the expression 15.5 - 0.5x evaluates to 19.5.
