Using the point slope form y - y1 = m(x-x1)
m is the slope, because the lines are parallel the slope is identical, so m = -2.
Replace x1 and y1 with the given point and then solve for y:
y - 1 = -2(x-4)
Simplify:
y - 1 = -2x + 8
Add 1 to both sides:
y = -2x +9
They are same side interior angles and same side interior angles are supplementary (add up to 180 degrees).
So, 6x+12+4x+18=180
Combine like terms:
10x+30=180
Subtract 30 from both sides:
10x=150
Divide both sides by 10:
x=15.
Therefore, the angles are same-side interior angles and x=15.
Answer:
The answer is 9 hours.
Step-by-step explanation:
you will have to divide 3 by 6 which is 0.50, which is half. Half of an hour is 30 minutes. Then you times that by 6 which is 180. 180 minutes is 3 hours. 3 hours is the amount of time it takes for six people. Now for the real question you will have to times 180 by 3 because 6 is 2 times 3. 3 times 180 is 460. 460 is 9 hours.
