A girl has 20 marbles
10 are red, 7 are blue, and 3 are green
If she picks 5 marbles, without replacing them, what are the chances all 5 are red?
10/20 * 9/19 * 8/18 *7/17 * 6/16
1/2 * 9/19 * 4/9 * 7/17 * 3/8
1/2 * 1/19 * 3/2
1/76
Answer:
D) The value cannot be determined from the information given
Step-by-step explanation:
If 3x−y=12, what is the value of 8x/2y ?
We can progress till:
- 3x-y=12
- y= 3x-12
- 8x/2y= 4x/y= 4x/(3x-12),
we need the value of x to determine the result.
So the answer is the last choice

Answer
Solution:
p = 79
n = 52
Step-by-step explanation:
Given equations:
A) 
B) 
To solve for 
and 
Naming the first equation as A and second as B.
Using elimination method to solve.
In order to eliminate we subtract equation A from B.
Subtracting A from B i.e [
(B)
- (A)
We get, 
Dividing both sides 2.26.
∴ 
We can solve for by substituting in equation A.
Subtracting both sides by 52.
∴
