Answer 1

(3,8-1.8)*3+2,4=2*3+2,4=8,4

Answer 2

Решение:

(t-1,8)*3+2,4

при усл, что t=3,8

3t-5,4+2,4

Первым действием выполняется -,

а значит

3t-3

(из 5,4 вычитаем 2,4)

Далее подставляем

3*3,8-3

11,4-3=8,4

Ответ:

8,4=8,4

Answer 3

Sure, I'd be happy to help you with the expression.

The expression is: (t - 1.8) * 3 + 2.4

Now, you provided the value of t, which is t = 3.8. Let's substitute this value into the expression and solve it:

Step 1: Substitute t = 3.8 into the expression. (3.8 - 1.8) * 3 + 2.4

Step 2: Perform the arithmetic operations inside the parentheses first. (2.0) * 3 + 2.4

Step 3: Multiply the value inside the parentheses by 3. 6.0 + 2.4

Step 4: Finally, perform the addition to get the result. 8.4

So, when t = 3.8, the value of the expression (t - 1.8) * 3 + 2.4 is 8.4.
