Question

4) (19n-6n): 4=26:5) (16m+5m): 18=7;6) (17n-8n) ​

Answer 1

Ответ:4) n=8

5)m=6

Пошаговое объяснение:4)19n-6n=13n

13n=26*4

13n=104

n=104/13=8

5)16m+5m=21m

21m=18*7

21m=126

m=6

Answer 2

Ответ:

4) 13n=26×4

13n=104

n=8

5) 21m=18×7

21m=126

m=6

6)9n

Answer 3

It seems like you've provided a series of mathematical expressions and equations. It looks like you want to solve these equations or simplify the expressions. Let's take a look at each one:

1. $\frac{19n - 6n}{4} = \frac{26}{5}$

   First, simplify the left side: $\frac{13n}{4} = \frac{26}{5}$

   Now, cross-multiply: $13n \cdot 5 = 26 \cdot 4$

   Solve for $n$: $65n = 104$

   Divide both sides by 65: $n = \frac{104}{65}$

   Simplify the fraction: $n = \frac{8}{5}$

2. $\frac{16m + 5m}{18} = 7$

   Combine the terms on the left side: $\frac{21m}{18} = 7$

   Simplify the fraction: $\frac{7m}{6} = 7$

   Divide both sides by 7: $m = 6$

3. $17n - 8n$

   Combine the terms: $9n$

It seems like the third expression doesn't have an equation associated with it. If you have more context or specific equations you want to solve, please provide additional information, and I'd be happy to assist you further.
