Answer 1

Ответ:

Пошаговое объяснение:

2-3=-1

1)8,5+8,2+28,6=45,1

2)16,28-16,3=0,21

16-20=-4

9a+9b=18×2=36

Answer 2

It looks like you've provided a series of mathematical expressions. Let's break down each expression:

1. $8.5 + 8.2 + 28.6$ Calculating this expression gives: $8.5 + 8.2 + 28.6 = 45.3$

2. $16.28 - 16.316 - 209a + 9b$ This expression involves variables $a$ and $b$, so it can't be simplified further unless you provide specific values for $a$ and $b$.

3. $270$ This is a constant value and doesn't require any calculation.

If you have specific values for variables $a$ and $b$ in the second expression, I can help you simplify it further.
