7m2 + 6.5n - 4n + 2.5m2 - n = 9.5m2 + 1.5n
3m + 7m + 1 = 10m + 1
-7m - 3m + 5m = -5m
If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
5m-12n
7m2 + 6.5n - 4n + 2.5m2 - n = 9.5m2 + 1.5n
3m + 7m + 1 = 10m + 1
-7m - 3m + 5m = -5m
If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
7m + 2 = 37 or 7m = 37 - 2 or 7m = 35 So m = 5
7m + 8 =71 7m = 71 - 8 7m = 63 m = 63/7 m = 9
9.20m - 7.30m = 1.9 metres.
5m-12n
The GCF is 7m.
-7m + 20 = -17m - 1010m = -30m = -3
Gather the m's and n's by rewriting it. 7m - 11n - n + 5m 7m + 5m -11n - n (7m + 5m) + (-11n - n) 12m - 12n ■
That depends on the value you give to 'm'.
