Answer:
option (3) is correct.

Step-by-step explanation:
Given 
We have to solve for e.
Consider the given statement,

Cross multiply, we get,

Taking square root both sides , we get,

We know square root of 9 is 3.

Thus, option (3) is correct.

Answer:
A, C, and D
Step-by-step explanation:
6 blue pencils and 3 red pencils means 9 total pencils. So the probability of pulling out ONE blue pencil would be 6/9 or about 67 percent. TWO blue pencils would be HALF of that. So 6/9 * 1/2 which is 6/18 or 1/3 or about 33 percent.
Answer:
3, -8
(x is equal to 3 and y is equal to -8)
Step-by-step explanation:
<u>The system:</u>
{ 7x=-67-11y
{ 5x=-73-11y
<u>Finding a value for x:</u>
7x=-67-11y -> x =
- 
<u>Solving for y by plugging in our x:</u>
[Equation] 5x = -73 -11y
[Plug-in] 5(
-
) = -73 -11y
[Distribute the 5]
-
= -73 -11y
[Multiply by 7] 7 (
-
) = (-73 -11y) 7
[Simplify] -335 - 55y = -511 - 77y
[Add 335 and 77y to both sides] 22y = -176
[Divide by 22] y = -8
<u>Plug in our y to solve for x:</u>
5x = -73 -11y
5x = -73 -11(-8)
5x = -73 + 88
5x = 15
x = 3
