2-

Пошаговое объяснение:

1 как известно 0,4x(-3)=-1,2 и 0,5-1,7=−1,2

то: x= -1,2=-1,2

2 1,7=6=7,7 (потому-что целое число всегда складывается с числителем передним числом)

Answer 2

To solve the given arithmetic expressions, let's break them down step by step:

1. 1,7 + 6 = 7,7 The sum of 1.7 and 6 is indeed 7.7.

2. 0,5 - 1,7 = 0,4 × (-3) The subtraction of 1.7 from 0.5 does not equal 0.4 multiplied by -3. Let's solve it correctly:

   0.5 - 1.7 = -1.2 The subtraction of 1.7 from 0.5 results in -1.2.

   Now, let's check if -1.2 is equal to 0.4 multiplied by -3:

   0.4 × (-3) = -1.2 Yes, the product of 0.4 and -3 is indeed -1.2, so both sides of the equation are equal.

Therefore, the correct equation is: 0,5 - 1,7 = 0,4 × (-3) and it is true.
