i am not a robot, but you should download this app called photo math and you jus take a picture of the problem and it does the work for you and it would probably answer this problem no sweat.
Step-by-step explanation:
The answer would be 27/1. You reverse it....
Probability of getting a red marble: 3/10
probability of getting a blue marble (after removing a red marble): 2/9
multiply the two fractions together:
6/90
simplify (divide by 6): 1/15 or .06666 repeating
Answer:
w= 6
Step-by-step explanation:
I just started by making an educated guess using the values already given. Then I inserted that into the problem to see if it worked.
L= 2w - 5
I used 6 as a random, educated guess for the value of w.
L = 2(6) - 5
L = 12-5
L = 7
Then, multiply L by 2 to account for both side lengths of the rectangle.
7(2)= 14
Subtract that value from the total perimeter to find what the width must equal.
26 - 14 = 12
Divide that answer by 2 since there are two sides for width.
12/2 = 6
I know this was kind of long, but I hope it helps! :)
