60/65 + 12/65 = 72/65 or 1 and 7/65
3b+4 = b+12 3b-b = 12-4 2b = 8 b = 4
8b = -65 so b = -8.125
12
B=61
65 + 65 + 65 + 65 + 65 + 65 + 65 + 65 + 65 + 65 + 65 + 65 = 65 x 12 = 780
12 + 65 = 77 (this is in base 10, of course).
60/65 + 12/65 = 72/65 or 1 and 7/65
Addition is commutative. That is, a + b = b + a for all a, b
3b+4 = b+12 3b-b = 12-4 2b = 8 b = 4
12(b + 1)(b + 1)
Yes. By the associative property, a + b + c = a + c + b.
-65
4
b=12
8b = -65 so b = -8.125
3 times a times a times b
