7. 28 : 3 — 57 98 – 23 - 4 + 24 34 + 13 : 5 28 : 2 — 13 - 4 (49 + 28) : 7 (64 + 24) : 4

Answer 1

1:-47
2:95
3:36,6
4:-3
5:19,25
6:22

Answer 2

It seems like you've provided a series of mathematical expressions separated by dashes. Let's break them down step by step:

1. 28 ÷ 3 = 9
2. 57
3. 98 - 23 - 4 + 24 = 95
4. 34 + 13 ÷ 5 = 34 + 2.6 = 36.6
5. 28 ÷ 2 = 14
6. 13 - 4 = 9
7. (49 + 28) ÷ 7 = 77 ÷ 7 = 11
8. (64 + 24) ÷ 4 = 88 ÷ 4 = 22

Now, let's put it all together based on your initial expressions:

28 : 3 — 57 = 9 — 57 = -48 98 - 23 - 4 + 24 = 95 34 + 13 : 5 = 36.6 28 : 2 — 13 - 4 = 14 — 13 - 4 = -3 (49 + 28) : 7 = 77 ÷ 7 = 11 (64 + 24) : 4 = 88 ÷ 4 = 22

So, the result of the given expressions is as follows: -48 95 36.6 -3 11 22
