Answer 1

Ответ:

Думаю так

Пошаговое объяснение:

1) 5+(10+m) =5+10+m=15+m

2) 96-(n+32) =96-n-32=64-n

3) 19+(-10-k) =19-10-k=9-k

4) (30+x) -x=30+x-x=30

5) c+(15+c) =c+15+c=2c+15

6) (2+y) -(y-10) =2+y-y+10=12

7) -(15-a) =-15+a

8) -20+(k-10) =-20+k-10=k-30

9) (m+x) -(-10-x) =m+x+10+x=m+2x+10

10) -(y+15) +(5y+6) =-y-15+5y+6=4y-9

2.) 73.32:((15.41-14.76) *1.6) +55.186:6.73=73.32:(0.65*1.6) +8.2=73.32:1.04+8.2=70.5+8.2=78.7

Answer 2

1. 5 + (10 + m) = 15 + m
2. 96 - (n + 32) = 64 - n
3. 19 + (-10 - k) = 9 - k
4. (30 + x) - x = 30
5. c + (15 + c) = 15 + 2c
6. (12 + y) - (y - 10) = 22
7. -(15 - a) = a - 15
8. -20 + (k - 10) = k - 30
9. (m + x) - (-10 - x) = m + x + 10 + x = m + 2x + 10
10. • (y + 15) + (5y + 6) = -y - 15 + 5y + 6 = 4y - 9

Now, let's calculate the given expression: 73.32 : ((15.41 - 14.76) * 1.6) + 55.186 : 6.73

First, let's simplify the expression inside the brackets: 15.41 - 14.76 = 0.65 0.65 * 1.6 = 1.04

Now, let's calculate the division outside the brackets: 73.32 : 1.04 = 70.5

Next, let's simplify the expression after the plus sign: 55.186 : 6.73 = 8.2

Finally, let's add the two results together: 70.5 + 8.2 = 78.7

Therefore, 73.32 : ((15.41 - 14.76) * 1.6) + 55.186 : 6.73 equals 78.7.
