The perimeter of regular octagon shaped swimming pool is 42 feet. what is the length of each side of the pool? a. 5 feet c. 5 feet 2 inches b. 5 feet 3 inches d. 5.2 feet

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

thats not a system of equations, that is a solution
