Answer:
P(yellow or red) =8/15
Step-by-step explanation:
There are 15 marbles, 3 green, 4 blue, and 5 red marbles.
3+4+5 = 12
That means there are 15-12 = 3 3 yellow marbles.
3 green,
4 blue
5 red
3 yellow
To find the probability of yellow or red, we add the number of yellow and red marbles together over the total number of marbles
P(yellow or red) = (yellow +red)/ total
= (3+5)/ 15
=8/15

n = 85
Answer
C. 85
Here are the two equations for this problem:
Let length = L
Let width = W
Equation No. 1 -
L = 2W
Equation No. 2 -
2L + 2W = 36
First simply substitute the value of ( L ) from the first equation into the second equation to solve for ( W ) as displayed below:
Equation No. 2 -
2L + 2W = 36
2 ( 2W ) + 2W = 36
4W + 2W = 36
6W = 36
W = 36 / 6
W = 6
Now, we substitute the value of ( W ) from the second equation into the first equation to solve for ( L ) as displayed below:
Equation No. 1 -
L = 2W
L = 2 ( 6 )
L = 12
Therefore, L = 2W and 2L + 2W = 36 are the correct equations for this problem.
