Answer:
x= 11
Step-by-step explanation:
or, 9x-18=81
or, 9x=81+18
or, 9x=99
or, x=99/9
or, x=11
2,317
Because you get 1,170 times .98 which equals 1,146.6. Then, you get 1,146.6 plus 1,170 and get 2,136.6 and to the nearest whole number it will be 2,317.
I think it’s A. If the first event is 3/5 and the second event is 3/5×2/5, the third will be 3/5(2/5)²=0.096, and the fourth will be 3/5(2/5)³=0.0384 so the 5th will be 3/5(2/5)⁴=0.01536.
