percentage = 24%% rate:= 6m/25m * 100%= 0.24 * 100%= 24%
25m x 6m x 18m = 2,700 cubic m
6m + 5n - 4m + 7n = 2m + 12n
15m + (2n-6m) + 11m = = 15m + 11m + 2n - 6m = 26m - 6m + 2n = 20m + 2n = 2(10m + n)
-0.5
6m + 20 = 9m - 4 24 = 3m m = 8
6m + 15 = 12 Subtract 15 from both sides: 6m = -3 Divide both sides by 6: m = -3/6 = -1/2
(2m + 1) and (6m - 1)
When m is 7, (6m + 3) is (42 + 3) = 45.(45)3 = 91,125
n - 6m = 8 n = 6m + 8
