Пошаговое объяснение:
-5/8(3,2m - 1. 3/5n) - 7,2(-4/9m + 2,5n) =
-5/8(32/10m - 8/5n) - 72/10(-4/9m + 25/10n) =
-160/80m + 40/40n + 288/90m - 1800/100n =
-2m + n + 3,2m - 18n =
(-2m + 3,2m) + (n - 18n) =
1,2m + (-17n) = 1,2m - 17n
m = -10; n = -0,1
1,2m - 17n = 1,2*(-10) - 17*(-0,1) = -10 - (-1,7) =
-10 + 1,7 = -8,3
Ответ: - 8,3
- 5/8 * (3,2m - 1 3/5n) - 7,2 * (- 4/9m + 2,5n) =
- 5/8 * (32/10m - 8/5n) - 72/10 * (- 4/9m + 25/10n) =
- 160/80m + n + 288/90m - 1800/100n = -2m + n + 3,2m - 18n = 1,2m - 17n
якщо m = - 10, n = - 0,1
1,2m - 17n = 1,2 * (- 10) - 17 * (- 0,1) = - 10 - (-1,7) = - 10 + 1,7 = -8,3
