Amy(A): D + 12
Doug(D):D
Ginger(G):2D
SumOfAll(S)=208 : Total points / sum of all three friends
(D+12)+D+2D=208
D+12+3D=208 - transpose 12 to the right side
4D=208-12
4D = 196 - divide both sides by 4
D=49
Therefore, Doug scored 49
Answer:
y=3x+14
Step-by-step explanation:
Well you already know that the slope is 3
parallel lines always have the same slope.
so then you plug in the point (-6,-4) into y=3x+b
-6 is x and -4 is y
-4=3(-6)+b
-4=-18+b
14=b
so your equation is y=3x+14

Answer:
9:100
Step-by-step explanation:
Turn 9% into a fraction by putting it over a hundred:
