please answer! Marbles in a bag are black, green, and purple. The ratio of black to green to purple is 2:5:8. What is the probability of getting a green?

1/3

Step-by-step explanation:

Probability= expected/favored outcomes/total outcomes

there are 5 green marbles, and 15 in total.

So:

5 green (what we want) / 15 total

5/15 can simplify to:

1/3

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
