Answer:
30% members have voted.
Step-by-step explanation:
Given:
Number of members voted = 3
Number of members didn't vote = 7
We need to find what percentage of people voted.
Solution:
First we will find the total number of members in the election.
Now we can say that;
The total number of members in the election is equal to sum of Number of members voted and Number of members didn't vote.
framing in equation form we get;
The total number of members in the election = 
Now we will find the percentage of people voted.
So we can say that;
Percentage of members voted can be calculated by dividing Number of members voted from The total number of members in the election and then multiplying by 100 we get;
Percentage of members voted = 
Hence 30% members have voted.
 
        
             
        
        
        
Answer:
(x,y)=(-2,-5)
Step-by-step explanation:
y=1/2x-4
y=-2x-9
(y=) 1/2x-4=-2x-9
 1/2x +2x=-9+4
 1/2x +4/2x=-5
 5/2x=-5
 5x=-5*2
 5x=-10
 x=-2
x=-2
y=-2x-9=-2*(-2)-9=4-9=-5
(x,y)=(-2,-5)
 
        
             
        
        
        
Answer:
1144 o 286
Step-by-step explanation:
Si pregunta por la cantidad de personas que se pesaron, la respuesta es (8/10) * (1430) = 8 * 143 = 1144.
 Si desea saber cuántas personas no se pesaron, la respuesta es 1430* (2/10) = 286
 
        
             
        
        
        
14^(7x) = 17^(-8-x)
Take the log of both sides:
7x*log 14 = -(8+x)*log 17, or 7x^log 14 = -8*log 17 - x*log 17.
Grouping the x terms, we get x(7*log 14 + log 17)= -8*log 17
Then:
              -8*log 17
x= --------------------------   (answer)
      7*log 14 + log 17
