Пошаговое объяснение:

-3,8×(5,3)-(-1,8)-(-4,7) = -20,14+1,8+4,7 = -341/25 = -13 (16/25 - дробь) = -13,64

Answer 3

It looks like you've provided a mathematical expression that needs to be evaluated. Let's break down the expression step by step:

-3 * 8.3 - (-1.8) - (-4.7)

First, we'll deal with the negations:

-3 * 8.3 = -24.9 -(-1.8) = 1.8 -(-4.7) = 4.7

Now, we can substitute these values back into the original expression:

-24.9 - 1.8 - 4.7

Now, perform the subtraction:

-31.4

So, the result of the expression is approximately -31.4.
