Answer:
B.
Step-by-step explanation:
You must first subtract 12 from 27, which marks out two answers. A, and D.
Then, if NAthan traveled 3 times as far s philip, then you would multiply by three. leaving you with the only option being,
B.
Point-slope form is y - y1 = m (x + x1)
First you need to find m [slope] by subtract y2 and y1 and divide it by the outcome of x2 - x1
13 - (-9) = 22
-2 - 9 = -11
22/-11 = -2
Plug in the first point (as instructed) into the equation.
y - (-9) = -2 (x - 9)
Simplify the beginning.
y + [9] = [-2] (x + [-9])
(The brackets are the fill in the blanks)
That’s the problem. Where are the steps?

Answer:
The carpenter can build the triangular frame by cutting the 12 foot piece by 2foot
Let's first break it down to the time 8 people need for one wall. That would be 10 minutes, right? If one person would have to do it in stead of 8, you'd expect him to take 80 minutes.
To paint 7 walls, he would nee 7x80 = 560 minutes. 10 people would do that 10 times faster, ie., 56 minutes.
I know puzzles like these always have a mindtrick. Did I miss anything?? ;-)
