Answer:
Step-by-step explanation:
Vertical angles are congruent.
8x = 2x +30
6x = 30 . . . . . . subtract 2x
x = 5 . . . . . . . . divide by 6
__
60y -40 = 40y +20
20y = 60 . . . . add 40-40y
y = 3 . . . . . . . .divide by 20
_____
<em>Check</em>
The 'x' angles are 8x° = 8·5° = 40°.
The 'y' angles are (40y+20)° = (40·3+20)° = 140°.
The angles are supplementary, as they are supposed to be.
Answer:
54 wpm
Step-by-step explanation:
This is a simple rate word problem and all we have to do is put these two numbers into words per minute which is essentially words divided by minutes
Basically, all we have to do is divide the number of words by the minutes to get our answer
So 702 divided by 13 is 54

Let a = aircraft 1 seats
Let b = aircraft 2 seats
Let c = aircraft 3 seats
From the information given above, let's make basic equations.
We can begin to plug in values we know.
We now know that the second aircraft has 138 seats. Now we can plug in this value to find the value of the other seats. Let's start with the first aircraft.
We now know that the first aircraft has 189 seats. Let's now finally solve for the third aircraft.
Finally, we know that aircraft 3 has 84 seats. To check our work, let's make sure that each of these values add up to 411.
This is true, therefore the values are correct.
Aircraft 1: 189 seats
Aircraft 2: 138 seats
Aircraft 3: 84 seats
