Answer 2

6*( d-2 1/3)+17при d= -0,5; 6(-7/6)+17=-7+17=10

Answer 3

To evaluate the given expression for the specified value of d, let's substitute d with the given value and perform the calculations step by step:

Given expression: 6 * (d - 2 1/3) + 17

Substitute d with -0.5: 6 * (-0.5 - 2 1/3) + 17

Now, let's simplify the expression:

Step 1: Convert the mixed number 2 1/3 to an improper fraction. 2 1/3 = (3 * 2 + 1) / 3 = 7 / 3

Step 2: Substitute the improper fraction back into the expression. 6 * (-0.5 - 7/3) + 17

Step 3: Perform the subtraction inside the parentheses. -0.5 - 7/3 = -0.5 - (7 / 3) = (-1.5 - 7) / 3 = -8.5 / 3

Step 4: Substitute the result back into the expression. 6 * (-8.5 / 3) + 17

Step 5: Perform the multiplication. 6 * (-8.5 / 3) = -51 / 3

Step 6: Simplify further. -51 / 3 = -17

Step 7: Substitute the result back into the expression. -17 + 17

Step 8: Perform the addition. -17 + 17 = 0

Therefore, when d = -0.5, the value of the expression 6 * (d - 2 1/3) + 17 is 0.
