Answer 2

Ответ:

1) -4+10=6

2) 7,5+(-3,5)=4

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

Answer 3

To solve the given equations, let's break them down one by one:

1. ... + (10) 6 = 4 Since the symbol "..." represents a missing number, let's assume it to be "x". The equation becomes: x + (10) 6 = 4 Multiply 10 by 6: x + 60 = 4 Now, isolate the variable "x" by subtracting 60 from both sides: x = 4 - 60 x = -56

Therefore, the missing number is -56.

2. (2) 7.5 + (...) = 4 Again, assuming the missing number as "y," the equation becomes: (2) 7.5 + y = 4 Multiply 2 by 7.5: 15 + y = 4 Now, isolate the variable "y" by subtracting 15 from both sides: y = 4 - 15 y = -11

Therefore, the missing number is -11.

3. ... + (-5,1) = -3 Assuming the missing number as "z," the equation becomes: z + (-5,1) = -3 Now, isolate the variable "z" by subtracting (-5.1) from both sides: z = -3 - (-5.1) z = -3 + 5.1 z = 2.1

Therefore, the missing number is 2.1.

To summarize, the missing numbers are:

1. -56
2. -11
3. 2.1
