Answer:
166 marbles
Step-by-step explanation:
O - 44 = L
O - 48 = J
O - 6 = L + J
I want to isolate O here
O = 44 + L
Plug it in
44 + L - 6 = L + J
38 + L = L + J
38 = J
Now we know that Jack has 38.
O - 48 = J
O - 48 = 38
O = 86
Now we know Oscar has 86.
O - 44 = L
86 - 44 = L
42 = L
Lily has 42.
38 + 86 + 42 = .....166
They have 166 coins altogether - Also Happy New Year!!! :D

Answer:
Angle 1: 95 degrees
Angle 2: 85 degrees
Angle 3: 95 degrees
Step-by-step explanation:
Vertical angles are opposite and equal so in this case angle 1 and 3 are vertical and so are 2 and 85°
So that means angle 2 also equals 85 degrees and because of supplementary angles the other angle must add up to equal 180 degrees
85 + ? = 180
?=95
So both angle 1 and 3 equal 95 degrees
