Answer:
On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.
Step-by-step explanation:
Helen gathred a total of 37 mushroons in three hours. On the first hour she gathered "x" mushroons, on the second hour she gathered "x + 7" mushroons and on the third hour she gathered "x + 6". Therefore the sum of mushrrons she gathered on each hour should be equal to the total she gathered as shown below:
37 = x + (x+ 7) + (x + 6)
37 = 3*x + 13
3*x + 13 = 37
3*x = 37 - 13
3*x = 24
x = 24 / 3
x = 8
On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.
Answer:
3/25
Step-by-step explanation:
3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles
P(green) = number of green / total = 4/10 = 2/5
We replace it
3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles
P(red) = number of red / total = 3/10
P(green, replace,red) =2/5*3/10 = 3/25
