Решите уравнения: (4s+s+6s) : 7=11 (23n+n+80) 10=170000 (5k+3k+7k) : 10=1203 (2h+8h) 17=1700 (16f-12f+f) : 25=56m+4m+15=375

Найдем корни уравнений.

1) (4 * s + s + 6 * s) / 7 = 11;

s * (4 + 1 + 6) / 7 = 11;

s * 11/7 = 11;

11 * s/7 = 11;

11 * s = 11 * 7;

11 * s = 77;

s = 77/11;

s = 7.

2) (23 * n + n + 80) * 10 = 170000;

104 * n = 17000;

n = 17000/104;

n = 163.46;

3) (5 * k + 3 * k + 7 * k) / 10 = 1203;

15 * k = 1203 * 10;

15 * k = 12030;

k = 12030/15;

k = 802;

4) (2 * h + 8 * h) * 17 = 1700;

10 * h = 1700/17;

10 * h = 100;

h = 100/10;

h = 10;

5) (16 * f - 12 * f + f) / 25 = 56;

6) m + 4 * m + 15 = 375;

5 * m = 375 - 15;

5 * m = 360;

m = 360/5;

m = 72.
