The mean height would be 155
I'm pretty sure you add all the sides up together. So I think the answer to this would be 61 but I'm not 100% sure
N + 4 / 3 = 1 / 3
Multiply both sides by 3 :
3* ( N + 4 / 3 ) = 3 * ( 1 / 3 )
∴
N + 4 = 1
Subtract 4 from both sides:
N + 4 - 4 = 1 - 4
N = - 3
hope this helps !.
<u>Answer:
</u>
The point slope form of the line that passes through (-8,2) and is parallel to a line with a slope of -8 is 8x + y + 62 = 0
<u>Solution:
</u>
The point slope form of the line that passes through the points
and parallel to the line with slope “m” is given as
--- eqn 1
Where “m” is the slope of the line.
are the points that passes through the line.
From question, given that slope “m” = -8
Given that the line passes through the points (-8,2).Hence we get

By substituting the values in eqn 1, we get the point slope form of the line which is parallel to the line having slope -8 can be found out.
y-2=-8(x-(-8))
On simplifying we get
y – 2 = -8(x +8)
y – 2 = -8x -64
y – 2 +8x +64 = 0
8x + y +62 = 0
Hence the point slope form of given line is 8x + y +62 = 0
Let pages written by Tom for a school report = x
Pages written by Jen for school report= 10 x
Pages written by Tom + Pages written by Jen = 396
→ x + 10 x = 396
→ 11 x =396
Dividing both sides by 11, we get
→ x =36,
Pages wrote by Tom= 36 pages
Pages wrote by Jen = 36 × 10=360 pages
