Answer: There are 1820 sets of four marbles other than lavender.
Step-by-step explanation:
Since we have given that
Number of red marbles = 3
Number of green marbles = 5
Number of lavender marbles = 1
Number of yellow marbles = 2
Number of orange marbles = 6
So, Total number of marbles = 3 + 5+ 1 + 2 + 6 = 17
We need to find the sets of 4 marbles other than lavender.
so, Number of total marbles other than lavender becomes = 17 -1 =16
Number of marbles in a set = 4
So, Number of ways becomes

Hence, there are 1820 sets of four marbles other than lavender.

Answer:
x=70, y=55
Step-by-step explanation:
Since the angle "y" and 2x-15 form a straight line, that means the sum of the angles, must be 180 degrees.
So using this we can derive the equation: 
The next thing you need to know is that the sum of interior angles of a triangle is 180 degrees, so if we add all the angles, we should get 180.
So using these we can derive the equation: 
So, in this case we simply have a systems of equations. We can solve this by solving for x in the second equation (sum of interior angles), and plug that into the first equation.
Original Equation:

Subtract 2y from both sides

Now let's plug this into the first equation

Plug in 180-2y as x

Distribute the 2

Combine like terms

Subtract 345 from both sides

Divide both sides by -3

So we can plug this into either equation to solve for x

Substitute in 55 as y


Subtract 110 from both sides

Given:
8:03 = 188 empty seats
8:10 = 160 empty seat
188 - 160 = 28 empty seats
8:10 - 8:03 = 0:07 minutes
28 / 7 minutes = 4 empty seats per minute
8:00 - 8:03 = 3 minutes
3 minutes * 4 seats per minute = 12 seats
188 + 12 = 200 empty seats at 8:00
8:15 - 8:10 = 0:05 minutes
5 minutes * 4 seats per minute = 20 empty seats
160 - 20 = 140 empty seats at 8:15
200 - 120 = 80 empty seats
80 empty seats / 4 empty seats per minute = 20 minutes
120 empty seats at 8:20.
8:00 = 200 empty seats
200 / 4 = 50 minutes
8:00 + 0:50 = 8:50 is the time when there are no empty seats left.
The answer would be
B) 1
hope this helps!
