Question 1:
The answer the last choice.
You need at least 2 points to form a line; thus, you can eliminate the second choice since it only uses 1 point.
You need at least 3 points to form a plane. You can eliminate the first and third choice because they only use 2 points to try to name the plane.
That leaves you with the last choice.
Question 2:
Vertical angles are congruent. 112 and 7x+7 are vertical angles.
We can form an equation.
Subtract both sides by 7
Divide both sides by 7
The second choice is your answer. Have an awesome day! :)

Answer:
Daniel had 108 stickers at first
Step-by-step explanation:
Number of Daniel's stickers = d
Number of Elle's stickers = e
Since Daniel had 80 more stickers than Elle, d = 80 + e
e = d - 80
Daniel gave 1/4 of his stickers to Elle, Daniel is left with (d - d/4) = 3d/4
Elle now has e + d/4 = d - 80 + d/4 = (5d/4) - 80 = (5d - 320)/4
Elle now gave 3/5 of her remaining stickers to Daniel:
Elle now has:
Daniel now has:
Daniel now had 92 more stickers than Elle
Multiply through by 20
30d - 960 = 10d - 640 + 1840
20d = -640 + 1840 + 960
20 d = 2160
d = 2160/20
d = 108
