Answer: 34
================================================
Work Shown:
S = sum of the first 8 numbers
S/8 = 40 is the mean of those first 8 numbers
S = 8*40
S = 320 so the first 8 numbers add to this value
-------
R = sum of the 12 remaining values
R/12 = 30
R = 12*30
R = 360 is what the other 12 values add to
-------
R+S = 360+320 = 680 is what all twenty values add to. Divide this by 20 to get the overall average
(R+S)/20 = 680/20 = 34
#22)
4(t - 8) + 20 = 5
Distribute the 4.
4t - 32 + 20 = 5
Combine like terms.
4t - 12 = 5
Add 12 to both sides.
4t = 17
Divide both sides by 4.
t = 4.25
#24)
17 = -5(3 + w) + 7
Distribute the -5.
17 = -15 - 5w + 7
Combine like terms.
17 = -8 - 5w
Add 8 to both sides.
25 = -5w
Divide both sides by -5.
w = -5
#26)
9 = -(r - 5) + 11
Distribute the -.
9 = -r + 5 + 11
Combine like terms.
9 = -r + 16
Subtract 16 from both sides.
-7 = -r
r = 7
Is each part of the garage is full there would be 1200 card in the parking garage
:) because 300 times 4 = 1200
The point-slope equation of the line is 
Step-by-step explanation:
The form of the point-slope equation is 
, where
- m is the lope of the line
is a point lies on the line
The slope of a line 
, where
and 
are two points on the line
∵ The line through (2 , 3) and (7 , 4)
∴ 
= 2 and 
= 7
∴ 
= 3 and 
= 4
- Substitute these value in the rule of the slope
∵ 
∴ the slope of the line is 
Let us substitute the value of the slope and the coordinates of point in the form of the equation
∵
∵ = 2 and = 3
∵
∴
The point-slope equation of the line is
