Answer: D) 10

============================================================

Explanation:

I'm assuming points M and N are midpoints of segments FD and FE respectively. If that's the case, then segment DE is twice as long compared to segment MN. We consider MN to be a midsegment.

So,

DE = 2*(MN)

3x-2 = 2*(x+4)

3x-2 = 2x+8

3x-2x = 8+2

x = 10

Solve for x. 3.rº 80° 20° A. 10 B. 20 C. 50 D. 80

ohaa [14]

Answer:

x = 20°

Step-by-step explanation:

The angle measures should add up to 180 degrees. So that leaves us with 100 degrees left to find if we take out the 80 given.

3x + 2x simplifies to 5x. 5x must equal 100.

100/5 = 20.

Therefore x = 20.

satela [25.4K]

Answer:

The answer is B. 14.7%.

Step-by-step explanation:

Given:

Estimated time need to complete project $17h$ .

Actually time needed $19\frac{1}{2}h$ = $\frac{39}{2}$ h.

Difference between the time $ET-AT$ = $\frac{39}{2}- 17\\=\frac{39}{2} -\frac{34}{2}\\ =\frac{5}{2}$ $=2.5h$ .

So, the percentage error is $\frac{2.5}{17}\times100\\ =\frac{250}{17} \\=14.70%$ .

Therefore, the answer is B. 14.7%.
