Question

1,6*(-5,3)-2,4*(-5,3)-4 4/5*5,3 с обьяснениями

Answer 1

Ответ:   -22

Пошаговое объяснение:

1,6*(-5,3)-2,4*(-5,3)-4 4/5*5,3=

-5,3* (1.6 -2.4 + 24/5) =

-5.5 * (1.6 -2.4 + 4.8) =

-5.5 * 4 =  -22

Answer 2

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

1. Multiply 1.6 by (-5.3): 1.6 * (-5.3) = -8.48 The product of 1.6 and (-5.3) is -8.48.

2. Multiply 2.4 by (-5.3): 2.4 * (-5.3) = -12.72 The product of 2.4 and (-5.3) is -12.72.

3. Multiply 4 4/5 by 5.3: 4 4/5 can be written as a fraction: 4 + 4/5 = 24/5 (24/5) * 5.3 = 127.2/5 = 25.44 The product of 4 4/5 and 5.3 is 25.44.

Now, let's substitute the values back into the expression:

1.6 * (-5.3) - 2.4 * (-5.3) - 4 4/5 * 5.3

-8.48 - (-12.72) - 25.44

To subtract a negative number, we can change it to addition:

-8.48 + 12.72 - 25.44

Next, let's perform the additions:

-8.48 + 12.72 = 4.24

4.24 - 25.44 = -21.2

Therefore, the value of the expression 1.6*(-5.3) - 2.4*(-5.3) - 4 4/5*5.3 is -21.2.
