Question

7+0,4*(6+x)-0,5*(4x-3) решите при x=10

Answer 1

7+0,4*(6+10)-0,5*(4*10-3=37

Answer 2

 сночало мы делаем скобки а потом приступаек к другим 
1)6+10 = 16
2)4*10+40
3)40-3=37
4)0,4*16=6,4
5)0,5*37=18,5
6)7+6,4=13,4
7)13,4-18,5=-5,1

Answer 3

To solve the expression for the given value of x, simply substitute x with 10 and then perform the operations step by step.

Let's solve the expression step by step:

1. Substitute x with 10: 7 + 0.4 * (6 + 10) - 0.5 * (4 * 10 - 3)

2. Perform the operations inside the parentheses: 7 + 0.4 * (16) - 0.5 * (40 - 3)

3. Continue with the remaining operations: 7 + 6.4 - 0.5 * 37

4. Perform the multiplication: 7 + 6.4 - 18.5

5. Finally, perform the addition and subtraction from left to right: 13.4 - 18.5 = -5.1

So, the result of the expression when x = 10 is -5.1.
