I have no problem answering but it wont let me open the pdf. I will gladly give you your points back just thought that you should know
6 = 2(x+8) - 5x
⇒ 2x+ 2*8 -5x= 6
⇒ (2x -5x)+ 16= 6
⇒ -3x = 6 -16
⇒ -3x = -10
⇒ x= -10/(-3)
⇒ x= 10/3
⇒ x= 3 1/3
The correct answer is B. 3 1/3~
The sound intensity of rustling leaves, y = 20 decibels
<u>Step-by-step explanation:</u>
y = 10logx
The sound intensity of rustling leaves is 100 times the reference intensity.
x = ratio of intensity of sound to reference to intensity
x = 100:1 or x = 100
y = 10 log(100) = 10 * 2 = 20 decibels
y = 20 decibels
Answer:
it would take 10 hours
Step-by-step explanation:
Answer:
15.9 centimeters
Step-by-step explanation:
the information we have is:
Perimeter: 
Number of sides of the polygon: 
since each side has equal length, we can use the following equation to find the measure of one side of the polygon, the equation for perimeter:
where n is the number of sides and 
is the length of each side.
So we clear for and we get:
and subtituting the known values:
each side is 15.6 centimeters long
