Question

110. 1) (12m - 5m) 4 = 252; 2) (4n + 3n) . 11 - 154; 3) 45 (4mm) = 3; 4) (19n - 6n) : 4 = 26: 5) (16m + 5m) : 18 - 6) (17n - 8n) - 13 - 3 Срочно

Answer 1

Відповідь: це точно вірно

Answer 2

1) (12 m = 6
m) +4 = 25 4
7 m * 4 =
- 15 4
28 m= 254
ms lA
2 (4n +8n) 11=154
7n * 11 * 154
77n = 15 4
n= 2
9) 45 : (4 m - m) =3
45 = (4 m - m) = 3, m + 0
45 ÷ (3 m)= 3
45:3
15 =3
/ 5 = 3 m
3 m = 15
m= 5

Answer 3

It looks like you've provided a set of equations. Let's solve them one by one:

1. $(12m - 5m) \times 4 = 252$ Simplifying inside the parentheses: $7m \times 4 = 252$ $28m = 252$ $m = 9$

2. $(4n + 3n) \times 11 - 154$ Simplifying inside the parentheses: $7n \times 11 - 154$ $77n - 154$

3. $45 \times (4mm) = 3$ Simplifying inside the parentheses: $180mm = 3$ $mm = \frac{3}{180}$ $mm = \frac{1}{60}$

4. $(19n - 6n) \div 4 = 26$ Simplifying inside the parentheses: $13n \div 4 = 26$ $13n = 104$ $n = 8$

5. $\frac{(16m + 5m)}{18} - 6$ Simplifying inside the parentheses: $\frac{21m}{18} - 6$ $\frac{7m}{6} - 6$

6. $(17n - 8n) - 13 - 3$ Simplifying inside the parentheses: $9n - 13 - 3$ $9n - 16$
