Answer 2

(-24+78+12-46)*(-13)-(-75):15=20*(-13)+75÷15=-260+5=-255.

Answer 3

Let's break down the expression step by step:

First, let's simplify the expression inside the parentheses:

(-24 + 78 + 12 - 46) = 20

Now we have:

20 * (-13) - (-75) / 15

Next, let's perform the multiplication:

20 * (-13) = -260

Now the expression becomes:

-260 - (-75) / 15

To simplify further, let's deal with the division:

-75 / 15 = -5

Substituting the division result, we have:

-260 - (-5)

To remove the double negative, we change the subtraction to addition:

-260 + 5

Finally, performing the addition:

-260 + 5 = -255

Therefore, the final result of the expression is -255.
