Question

(16m+5m): 18=7;6) (17n-8n) · 13=351.​

Answer 1

Ответ:

6;3

Пошаговое объяснение:

(16m+5m):18=7

21m:18=7

21m=126

m=126:21

m=6

(17n-8n)×13=351

9n×13=351

9n=351:13

9n=27

n=27:9

n=3

Answer 2

To solve the equations, let's start with the first one:

(16m + 5m) / 18 = 7

Combine like terms in the numerator:

21m / 18 = 7

Now, divide both sides by 21/18:

(21m / 18) * (18 / 21) = 7 * (18 / 21)

This simplifies to:

m = (7 * 18) / 21

Now, calculate the value of m:

m = (126) / 21 m = 6

So, the solution to the first equation is m = 6.

Now, let's move on to the second equation:

(17n - 8n) * 13 = 351

Combine like terms in the parentheses:

9n * 13 = 351

Now, multiply 9n by 13:

117n = 351

To solve for n, divide both sides by 117:

n = 351 / 117

Simplify:

n = 3

So, the solution to the second equation is n = 3.
