Answer:
x = 9
Step-by-step explanation:
A line segment parallel to a side of a triangle and intersecting the other 2 sides divides the 2 sides in proportion, that is
8(3x - 20) = 56
24x - 160 = 56 ( add 160 to both sides )
24x = 216 ( divide both sides by 24 )
x = 9
Answer:
The value of x = 9
Step-by-step explanation:
From the figure
we can see that, the middle line segment is parallel to one side of the triangle.Therefore we can write,
9/72 = (3x - 20)/56
9*56 = 72(3x -20) [cross multiplying]
56 = 8(3x - 20) [divided by 9]
7 = 3x - 20 [divided by 8]
3x - 20 = 7
3x = 27
x = 27/3 = 9
Therefore the value of x = 9

Answer:
7 sheets of paper
Step-by-step explanation:
$40-$19=$21
$21/$3=7 sheets of paper.
In words:
I did 40 minus 19 to get 21, and the divided 21 by 3 to get 7 sheets of paper.
