You have to combine equal terms. -5r-9s+9r+3s-6 = -5r+9r-9s+3s-6 = 4r-6s-6
Eleven.
99 plus 9/9 = 100
20
Exactly 6 of them
11
6 of them with a remainder of 4
11 with 1 remaining 100 - 1 = 99 = 9 x 11
9^2+9+9 +9/9 81+9+9+1=100
One way: 99 + 9/9 = 100
The GCF of 9s and 63s^3 is 9s.
To get 100 using five 9s, you can use the following mathematical expression: (99 + 9/9) = 100 This equation involves adding 99 to the result of 9 divided by 9, which equals 1. This gives you a total of 100 using five 9s.
