Question

6m + 12n − 5m − 4n, якщо n = 3 8 , y=7

Answer 1

Відповідь: 311

Розв'язання:

6m + 12n − 5m − 4n = m + 8n, якщо  n = 38, m = 7, то 7 + 8 * 38 = 7 + 304 = 311

Answer 2

To evaluate the expression 6m + 12n - 5m - 4n when n = 38 and y = 7, simply substitute the values of m and n into the expression and perform the calculations:

Given n = 38 and y = 7

Expression: 6m + 12n - 5m - 4n

Substitute n = 38 and y = 7:

6m + 12 * 38 - 5m - 4 * 38

Now, perform the calculations:

6m + 456 - 5m - 152

Combine like terms:

(6m - 5m) + (456 - 152)

Simplify:

1m + 304

Now, substitute y = 7:

1 * 7 + 304

7 + 304

Final answer:

311
