=-120:(-60)-72=

=2-72=-70

Ответ: -70

2) -144:(42-46)-12×(-3)=

= -144:(-4)+36=

= 36+36=72

Ответ: 72

Answer 2

1) -120:(-26-34)+36•(-2)= -120:(-60)-72=2-72= -70
2) -144:(42-46)-12•(-3)= -144:(-4)+36=36+36=72

Answer 3

Let's solve the expressions step by step:

1. -120 : (-26 - 34) + 36 * (-2)

First, perform the operations inside the parentheses:

-26 - 34 = -60

Now the expression becomes:

-120 : (-60) + 36 * (-2)

Next, perform the division:

-120 ÷ (-60) = 2

Now the expression becomes:

2 + 36 * (-2)

Next, perform the multiplication:

36 * (-2) = -72

Now the expression becomes:

2 + (-72)

Finally, perform the addition:

2 + (-72) = -70

So, the result of the first expression is -70.

2. -144 : (42 - 46) - 12 * (-3)

First, perform the operations inside the parentheses:

42 - 46 = -4

Now the expression becomes:

-144 : (-4) - 12 * (-3)

Next, perform the division:

-144 ÷ (-4) = 36

Now the expression becomes:

36 - 12 * (-3)

Next, perform the multiplication:

12 * (-3) = -36

Now the expression becomes:

36 - (-36)

Finally, perform the subtraction:

36 - (-36) = 72

So, the result of the second expression is 72.
