You have to turn 65 into a decimal. That would be .65
They do 39/.65
You should get 60 as your final answer.
This is a more difficult one to explain. Let's start with the line to the right. It has a slope (m) of 
= -1 and a y-intercept of +3 (continue the line to see where it crosses the y-axis). So, the equation of that line is: y = -x + 3 when x ≥ 2. This can also be written as y = 3 - x when x ≥ 2. The only option that has that equation is A.
Answer: A
Answer:
The bottom is 11
The median is 12
Step-by-step explanation:
The median is the average of the top and bottom
(13+ 2x-3) /2 = 4x-16
Combine like terms
(10+2x)/2 = 4x-16
Divide by 2
5+x = 4x-16
Subtract x from each side
5+x-x = 4x-16-x
5 = 3x-16
Add 16 to each side
5+16 = 3x-16+16
21 = 3x
Divide by 3
21/3 = 3x/3
7 =x
The bottom is 2x-3 = 2*7-3 = 14-3 = 11
The median is 4x-16 = 4*7-16 = 28 -16 = 12
Step-by-step explanation:
x+4=19-2x
Im pretty sure Im right!
Answer:
The percentage error of measurement is 5.63 %
Step-by-step explanation:
Given as :
The measure length of the fence = 150 feet
The actual length of the fence = 142 feet
Let the percentage error in measurement = x
So, x = 
×100
Or, x = 
×100
or, x = 
×100
or, x = 5.63 %
Hence The percentage error of measurement is 5.63 % Answer
