Объяснение:

Я не знаю правильно ли это или нет но у меня вышло 13х-33

Answer 3

To evaluate the expression 5(3x - 7) + 2(1 - x) when x = 526, we substitute the value of x into the expression and perform the calculations.

Let's replace x with 526:

5(3(526) - 7) + 2(1 - 526)

Now, simplify the expression:

5(1578 - 7) + 2(1 - 526) 5(1571) + 2(1 - 526)

Perform the calculations inside the parentheses:

5(1571) + 2(-525) 7855 + 2(-525)

Multiply:

7855 - 1050

Perform the subtraction:

6805

Therefore, when x = 526, the expression 5(3x - 7) + 2(1 - x) evaluates to 6805.
