Question

{-30}*2-{-15}*[-4}и 0,15*{-60}-8,9;

Answer 1

$(-30)\cdot2-(-15)\cdot(-4)=-60-60=-120\\\\0,15\cdot(-60)-8,9= -9-8,9=-17,9$

Answer 2

The expression you provided seems to contain a few errors. Let's correct those errors and evaluate the expression:

(-30) * 2 - (-15) * [-4] + 0.15 * (-60) - 8.9

First, let's simplify the expression within the square brackets:

(-15) * [-4] = 60

Now, let's substitute the simplified expression back into the original expression:

(-30) * 2 - 60 + 0.15 * (-60) - 8.9

Next, let's perform the multiplications and additions/subtractions:

(-30) * 2 = -60 0.15 * (-60) = -9 -60 - 9 = -69

Finally, let's combine the results:

-60 - 69 - 8.9 = -137.9

Therefore, the evaluated value of the expression is -137.9.
