2 точно. .......................

Answer 3

To evaluate the expression 3m - 2n when m = -1 and n = -2.5, substitute these values into the expression:

3m - 2n = 3(-1) - 2(-2.5)

Now, perform the calculations step by step:

3(-1) = -3 2(-2.5) = -5

Now, combine the results:

3m - 2n = -3 - (-5) = -3 + 5 = 2

So, the value of 3m - 2n when m = -1 and n = -2.5 is 2. Option 2 is correct.
