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:

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.

Help with Geometry Homework Please?
Harrizon [31]
The answer for the first slot is Alternate Interior Angles Theorem
Angle B and angle G are inside the "train tracks" formed by AB and GH. They are on opposite sides of the transversal line BG.

Along a similar line of reasoning, the answer for the second slot is Alternate Exterior Angles Theorem
The two parallel lines in question are AC and FH. The transversal line is FC. Angles ACB and HFG are on the exterior of the "train tracks" formed by the parallel lines.

1 QUESTION. PLEASE HELP. VOLUME GEOMETRY QUESTION.
mina [271]
Knowing the volume of a 3-D shape is extremely when deciding what materials to use and how much of them to use.  When you know the volume of the different designs is helpful when deciding which material costs less to use but still meets requirements. For example, if you were trying to decide what material to fill your product with, and say the volume of your product is 36^3. You narrow things down to two products, one costing $54 to fill the entire thing. The other costing $60. Because you have the volume, it will be easy to decide which is better based off of the price per square inch. If you didn't have the volume. You would have to make an estimate and potentially make a bad business decision.   

Hope this helps! I apologize for my long response

nikitadnepr [17]

Answer:

3/13

Step-by-step explanation:

8/13 subtract by 5/13. If the denominator is the same, you keep it, don't change it. Just subtract the numerator.

Make sure to simplify, if it is already simplified that will be the answer.
