Answer:
2n-8
Step-by-step explanation:
twice n is 2n. decreased by 8 is the -8

The total length of line segment FH = 140
We have a line segment FH and G is its midpoint such that - FG = 14x + 25 and GH = 73 – 2x.
We have to find FH.
<h3>What is Line Segment?</h3>
A line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length.
According to question, we have -
FG = 14x + 25.
GH = 73 – 2x.
Since, G is the midpoint of line FH, therefore -
FG = GH
Now -
FG = GH
14x + 25 = 73 – 2x
14x + 2x = 73 - 25
16x = 48
x = 3
Therefore, the total length of the Line segment is -
FG + GH = 14x + 25 + 73 – 2x
Substitute x = 3, we get -
FH = 14 x 3 + 25 + 73 - 2 x 3 = 73 + 67 = 140
Hence. the total length of line segment FH = 140

Answer:
the coins and stamps do each of you collect is 25, 45, 5 and 90 respectively
Step-by-step explanation:
The computation is shown below:
For you
Let us assume the coins be x
Let us assume the stamps be y
For friend
The coins be 1 ÷ 5x = 0.2x
And, the stamps be 2y
Now the equations are
x + y = 70
y = 70 - x
Now put the value of y in other equation
0.2x + 2y = 95
0.2x + 2(70 - x) = 95
0.2x + 140 - 2x = 95
-1.8x = -45
x = 25
And, y = 70 - 25
= 45
And, for your friend it is
= 25 × 1 ÷ 5
= 5
And, the stamps be
y = 45 × 2
= 90
Hence, the coins and stamps do each of you collect is 25, 45, 5 and 90 respectively
