Question

-6(2t-3,6)-25,2t-6,если T=-1/2 Сначала упростите выражение

Answer 1

=-12t+21,6-25,2t-6=-13,2t+15,6=-13,2•(-1/2)+15,6=6,6+15,6=22,2

Answer 2

To simplify the expression, let's start by substituting the value of T:

T = -1/2

Now, we'll simplify the given expression step by step:

-6(2T - 3, 6) - 25 + 2T - 6

Step 1: Replace T with -1/2

-6(2*(-1/2) - 3, 6) - 25 + 2*(-1/2) - 6

Step 2: Simplify the expression inside the parentheses:

-6(-1 - 3, 6) - 25 - 1 - 6

Step 3: Continue simplification:

-6(-4, 6) - 25 - 1 - 6

Step 4: Simplify the expression inside the parentheses:

-6(-10) - 25 - 1 - 6

Step 5: Perform the multiplication:

60 - 25 - 1 - 6

Step 6: Perform the addition and subtraction:

(60 - 25) - 1 - 6

35 - 1 - 6

Step 7: Perform the remaining addition and subtraction:

34 - 6

Step 8: Final result:

28

So, after simplifying the given expression when T = -1/2, the result is 28.
