Question

Find the value of x to the nearest tenth. 10.0 6.0 9.3 4.0

Answer 1

Suppose that the value of other ratio is equal to 6/3 then,

20/3x-8 = 6/3
18x-48 = 60
18x = 60+48
18x = 108
x = 6

Answer 2

Answer:

The value of x is 6  

Step-by-step explanation:

Given the figure in which

DE=3x-8 and BC=20

we have to find the value of x.

By mid-point theorem which states that the line segment which is drawn to the mid-points of two sides of triangle is parallel to the third side and also half of the length of third side.

$DE=\frac{1}{2}BC$

$(3x-8)=\frac{1}{2}\times 20$

$3x-8=10$

$3x=18$

$x=\frac{18}{3}=6$

The value of x is 6

Option 2 is correct.
