Answer:
see ur question is easy
Step-by-step explanation:
x + 2x + 5x = 180
6x =180
x= 180/6
x= 30
To determine the 5th term you need to find the 4th. This doesn’t work for all but for this one you just add a zero at the end. So the 4th term is 1,000 and that makes the 5th term 10,000
There are 30 total integers. 10 of these will be divisible by 3 (all multiples of 3 between 3 and 30). So the probability of getting an integer evenly divisible by 3 is

.
Answer: 56
Step-by-step explanation:
The perimeter is just adding up all of the sides and we know an octagon has 8 sides, so you can just do 8 by 7 which is 56.
