Answer:
6
Step-by-step explanation:
x+6-10=2
x+6=12
x=12-6

Step-by-step explanation:
The probability of having high blood pressure is 17%.
We need to find the probability of 2 or fewer have high blood pressure.
Possibility 1: No one have high blood pressure.
The probability is  .
.
Possibility 2: Only one have high blood pressure.
The probability is  .
.
Possibility 3: 2 among the 10 have the high blood pressure.

Any of the possibilities can happen.
Hence, the required probability is  +

Answer:
(1,0)
Step-by-step explanation:
3x + 6y = 3 
 7x + 3y = 7
Multiply the second equation by -2
-2( 7x + 3y = 7)
-14x -6y = -14
Add this to the first equation to eliminate y
3x + 6y = 3
-14x -6y = -14
--------------------
-11 x = -11
Divide by -11
x = 1
Now find y
3x + 6y = 3
3 +6y = 3
Subtract 3 from each side
6y = 0
y =0
 
        
                    
             
        
        
        
7x+y=11 where y= -5                                                                                              So, when we substitute y in the equation then,
7x + (-5) = 11 that is 7x - 5 = 11....
So, B. is the right answer.
