Question

6d+15c*d-7c если c=0,1 d=0,2

Answer 1

Ответ:

0,8

Пошаговое объяснение:

6d + 15c * d - 7c при c = 0,1 , d = 0,2

6d + 15 (0,1) * d - 7 * 0,1

6 (0,2) + 15 (0,1) * (0,2) - 7 * 0,1

1,2 + 0,3 - 0,7

Ответ: 0,8

Answer 2

To evaluate the expression when c=0.1 and d=0.2, simply substitute these values into the expression:

6d + 15c * d - 7c

c = 0.1 d = 0.2

Now, plug in the values:

6 * 0.2 + 15 * 0.1 * 0.2 - 7 * 0.1

Calculate each part:

1.2 + 0.3 - 0.7

Now, perform the additions:

1.2 + 0.3 = 1.5

Finally, subtract:

1.5 - 0.7 = 0.8

So, when c=0.1 and d=0.2, the value of the expression is 0.8.
