M = 22
The answer is 22.02 meters
240 m3 - without using a calculator !
-3m = 5m+8 -3m-5m = 8 -8m = 8 m = -1
8m + (4n - 6m) + 9n =8m + 4n - 6m + 9n =(8m - 6m) + (4n + 9n) =2m + 13n
m=-21/2 or m=-10.5
10m 7m 7m
8m + 7 = -98m = -16m = -2
If: 8m = 32m+96 Then: m = -4
21
.230
m = 4
M = 22
40
7 - 14m
No
4m+15=8m-5 or,4m=20 or,m=5
