Пошаговое объяснение:

5|a|-5|b| если а=7,9,b=1

5|7,9|-5|1| =5*7,9-5*1 = 39,5 - 5 = 34,5

Answer 2

Ответ:

5*7,9=39,5

39,5-5=34,5

Answer 3

To evaluate the expression 5|a| - 5|b| when a = 7.9 and b = 1, we substitute the given values into the expression:

5|7.9| - 5|1|

The absolute value of a number is always positive, so |7.9| is equal to 7.9. Similarly, |1| is equal to 1. Substituting these values:

5 * 7.9 - 5 * 1

= 39.5 - 5

= 34.5

Therefore, when a = 7.9 and b = 1, the value of 5|a| - 5|b| is 34.5.
