Question

2.1)-3,2+1,72)-3,7-(-1,3)3)(5,3-7,1)•(-0,3)​

Answer 1

Ответ:

1) -1,5;

2) -2,4

3) 0,54

Пошаговое объяснение:

1) -3,2 + 1,7 = -1,5

2) -3,7 - (-1,3) = -2,4

3) (5,3 - 7,1) × (-0,3) = -1,8 × (-0,3) = 0,54

Answer 2

Ответ:

1) -1,5;

2) -2,4

3) 0,54

Пошаговое объяснение:

1) -3,2 + 1,7 = -1,5

2) -3,7 - (-1,3) = -2,4

3) (5,3 - 7,1) × (-0,3) = -1,8 × (-0,3) = 0,54

Answer 3

It looks like you have an expression with multiple operations. Let's break it down step by step:

1. 2.1 - 3 = -0.9
2. 2 + 1.72 = 3.72
3. -3.7 - (-1.3) = -3.7 + 1.3 = -2.4
4. 5.3 - 7.1 = -1.8
5. -0.3

Now, let's multiply the results:

-0.9 * 3.72 = -3.348 -2.4 * (-1.8) = 4.32

Finally, let's multiply the two results:

-3.348 * 4.32 = -14.45136

So, the final result is approximately -14.45136.
