Use a definition, postulate, or theorem to find the value of x in the figure described. Point E is between points D and F. If DE
Afina-wow [57]

Answer:

Option (D)

x = 5

Step-by-step explanation:

Since point E is in the mid of the segment DF,

Therefore, by the Segment addition postulate,

DF = DE + EF

Since DF = (8x - 3), DE = (x - 3) and EF = (6x + 5)

By substituting these values in the given postulate,

(8x - 3) = (x - 3) + (6x + 5)

8x - 3 = (x + 6x) + (5 - 3)

8x - 3 = 7x + 2

8x - 7x = 3 + 2

x = 5

Therefore, x = 5 will be the answer.

there are 14,240 books in the library. they are arranged on shelves that hold 8 books each. How many shelves are i the library
SashulF [63]

First off, it sounds strange to learn that each shelf holds only 8 books each.

But if that's the case, then the library has (14,240 books) / (8 books per shelf), or 1,780 shelves.

Explain how to find the number of grams of fat in 2.5 cups of corn if there are 7.87 grams of fat in 1 cup of corn
Alina [70]
7.87g/2.5cups= 3.148 (3.15)

3.15+3.15=6.30

3.15/2=1.575 (1.58)

6.30+1.58=7.88

So approximately 3.15 grams of fat equals 2.5 cups of corn
