Answer:

She drove 200km at 100km/hr and she drove 240km at 80km/hr

Step-by-step explanation:

2×100km/hr=200km and 80km/hr×3=240km/hr

200km+240km=440km

(2+3=5)

79-y=2y+22

Add y on both sides

79=3y+22

Subtract 22 from both sides

57=3y

Divide by 3 on both sides

19=y

Which of the following is the best definition of vertical angles?
Lilit [14]

Step-by-step explanation:

Very quick and effortless example of vertical angles in the attached image. When 2 straight lines intersect, the 2 angles opposite each other at that point are vertical angles, and they are always congruent.

I'd say it's the 3rd option:

"Vertical angles are a pair of non-adjacent angles formed by two intersecting lines."

but any of the first three could be technically true really. Adjacent angles are 2 angles that share a side, and vertical angles cannot share one.
