Answer:
none of the options
Step-by-step explanation:
4x − 5y = 2 , 10x − 21y = 10
---------
the first equation is same in all answer choices, let's check which is equivalent to second, the easy way is to consider x/y ratio which is 10/ -21
4x − 5y = 2 , 3x − y = 4
4x − 5y = 2 , 24x − 47y = 22
4x − 5y = 2 , 10x + 3y = 15
4x − 5y = 2 , 14x + 26y = 12

Answer:
the total of marbles = 7 red + 11 blue + 7 Yellow
= 25 marbles
P ( b n r) = 11/25 + 7/24
=0.732
Step-by-step explanation:
1. find the total marbles
2. find the probability of each without replacement means the demoinator will reduce
3.add the two probability
This is the correct answer: 3x^3 - x^2 + 6x - 9
