4.5w = 5.1w -30
4.5w - 5.1w = 5.1w - 5.1w -30 (subtracted 5.1w on both sides)
4.5w - 5.1w = -30 (next combine like terms)
-0.6w = -30 (next do the inverse operation of w)
w = -30 ÷ -0.6
w = 50 (it became positive cause minus and minus = positive)
so your final answer is: w = 50
Hope that helps:D
Answer:

-12x = 60
Step-by-step explanation:
This is the type of problem that you just have to do a bunch of times until you get it right -- I don't think there's anything I can tell you that'll help you immediately. Ask for your teacher for more exercises of this sort or look it up online.
Good luck!
Answer:
$41.9
Step-by-step explanation:
divide $62.85 and get 20.95 which is 1/3 of it so then you just subtract $20.95 from $62.85 and get 41.9
Step-by-step explanation:
The angles on the same side of the parallel lines and the transversal are called corresponding angles.
Corresponding angles are congruent
So 11x+1 = 10x+10
x = 10-1 = 9
11*9+1 = 100
So both are 100 degrees
