Answer 1

Пошаговое объяснение:

(-70-11,25×0,8)×(-30+(-0,8)×(6,25)) - 37= 2728

1) 11,25*0,8=9

2) -70 -9= - 79

3) -0,8 * 6,25=-5

4) -30-5=- 35

5) -79 * (-35)= 2765

6) 2765-37= 2728

Answer 2

To solve the given expression, let's break it down step by step:

(-70-11,25×0,8)×(-30+(-0,8)×(6,25)) - 37​

First, we calculate the expressions within the parentheses:

(-70 - 11.25 × 0.8) equals -70 - 9 = -79.

(-0.8) × (6.25) equals -0.8 × 6.25 = -5.

Next, we substitute the calculated values back into the original expression:

(-79) × (-30 + (-5)) - 37

(-79) × (-30 - 5) - 37

(-79) × (-35) - 37

Multiplying -79 by -35 gives us 2,765.

2,765 - 37 equals 2,728.

Therefore, the result of the expression (-70-11,25×0,8)×(-30+(-0,8)×(6,25)) - 37 is 2,728.
