If you do 60% then you put the percent two times over the the left so 0.60 then you would do 0.60 times 50 so that would be 30. 30 of the members must vote. Hopefully that helped?
Answer:
5x+4
Step-by-step explanation:
use the equation mx+b I think this is right but I really dunno
To find the average, you have to add all the numbers up and then divide by the amount of numbers you added together.
Equation: (86+87+91+x)/4=98
Solve for x:
86+87+91+x=98*4
264+x=392
x=392-264
x=128
The fourth number is 128
Sum = 20(1-(1/4)^5) / (1-1/4) = 26.64
