9x + 6 + 2(5x-3) + 5y +14
9x + 6 + 10x - 6 + 5y +14
19x + 5y + 14
19x = -5y -14
x = -5y/19 - 14/19
Answer: 0.089
Step-by-step explanation:
Number of combinations of n things taking r at a time :-

Given : A box has eight green marbles, five red marbles, and seven blue marbles.
Total marbles = 5+8+7=20
We choose three marbles from the box at random without looking.
Number of ways to choose 3 marbles with same color :-
(1)
Total ways to select 3 marbles from 20 marbles :-
(2)
Now, the required probability (divide (1) by (2)):-

Hence, the required probability : 0.089
5.5 always goes between 5 and 6
remember (x,y) one of the dots goes on the exactly on the axis, you have to drag it down to -9 from the y-axis
