Answer:
-0.7(4x+9)
Step-by-step explanation:
-2.8x-6.3=-0.7(4x+9)
I think 12 might be the second one, I'm not sure though!
Because of rules of geometry we know that a+b=180 degrees so we can add the equations together and set that equal to 180 and solve
6x-48+4x+38=180
subtract 38 from both sides and add 48 to both sides
then add like terms
10x=170
and divide by 10 to get
x=17
2:1 is the ratio
