Question

3. В программе «:=» обозначает оператор присваивания, знаки «+», «-», «*» и «/» — соответственно операции сложения, вычитания, умножения и деления. Правила выполнения операций и порядок действий соответствуют правилам арифметики. Определите значение переменной b после выполнения алгоритма: а := 7 b := 4 а := 2*а + 3*b b := a/2*b Срочно помогите

Answer 1

Ответ:

52

Объяснение:

а := 7

b := 4

а := 2*7 + 3*4

b := 26/2*4

Answer 2

Explanation

The given algorithm involves a series of assignments and arithmetic operations. Let's break down the algorithm step by step to determine the value of the variable `b` after its execution.

1. `a := 7`: This assigns the value 7 to the variable `a`. 2. `b := 4`: This assigns the value 4 to the variable `b`. 3. `a := 2 * a`: This multiplies the current value of `a` (which is 7) by 2 and assigns the result (14) back to `a`. 4. `3 * b`: This multiplies the current value of `b` (which is 4) by 3, resulting in 12. 5. `b := a / 2 * b`: This performs two operations: division and multiplication. First, it divides the current value of `a` (which is 14) by 2, resulting in 7. Then, it multiplies the result (7) by the current value of `b` (which is 12), resulting in 84. Finally, it assigns the result (84) back to `b`.

Therefore, after executing the given algorithm, the value of the variable `b` will be 84.
