Answer:

Step-by-step explanation:
The vertical angles have the same measure, so ...
3x +50 = 6x -10
60 = 3x . . . . . add 10-3x
20 = x . . . . . . divide by 3
Answer:
(3,-3)
Step-by-step explanation:
First you divide 2 out of the first equation and it turns into 5x+y=12.
Then you write one on top of the other so you can add them. It looks like:
5x + y = 12
-5x + y = -18
Then you add them together and the 5x's cancel each other out and you are left with 2y = -6
So then you divide both sides by 2 and get y = -3
Then you plug -3 into the second equation because it is simpler and get -5x - 3 = -18
So then you add three to both sides and get -5x = -15
And finally you divide both sides by -5 and get x=3
Answer: 180ft
Step-by-step explanation: distance = speed * time 30ft/min * 6min = 180 ft
Answer: $36.13
Step-by-step explanation:
50 x .15 = 7.5
50 - 7.5 = 42.5
42.5 x .15 =6.375
42.5 - 6.375 = 36.125
36.125 rounded is 36.13
