Answer 2

Пошаговое объяснение:

1) 56:(-7)+3=-8+3=-5

2) -8*(-5)+75:(-15)= 40+(-5)=35

3) (12-28):(-4)*5=-16:(-4)*5= 4*5=20

Answer 3

Let's solve each of these expressions step by step:

1. 56 : (-7) + 3

First, we'll calculate 56 divided by -7:

56 / (-7) = -8

Now, add 3 to this result:

-8 + 3 = -5

So, the answer is -5.

2. -8 * (-5) + 75 : (-15)

First, we'll calculate -8 multiplied by -5:

-8 * (-5) = 40

Now, we'll calculate 75 divided by -15:

75 / (-15) = -5

Now, add these results together:

40 + (-5) = 35

So, the answer is 35.

3. (12 - 28) : (-4) * 5

First, calculate 12 - 28:

12 - 28 = -16

Now, divide -16 by -4:

-16 / (-4) = 4

Finally, multiply the result by 5:

4 * 5 = 20

So, the answer is 20.
