Answer: -19, -23, -27
Step-by-step explanation:
You minus/subtract 3 each time to get your next three terms

Answer: Choice B</h3>
With matrix subtraction, you simply subtract the corresponding values.
I like to think of it as if you had 2 buses. Each bus is a rectangle array of seats. Each seat would be a box where there's a number inside. Each seat is also labeled in a way so you can find it very quickly (eg: "seat C1" for row C, 1st seat on the very left). The rule is that you can only subtract values that are in the same seat between the two buses.
So in this case, we subtract the first upper left corner values 14 and 15 to get 14-15 = -1. The only answer that has this is choice B. So we can stop here if needed.
If we kept going then the other values would be...
row1,column2: P-R = -33-16 = -49
row1,column3: P-R = 28-(-24) = 52
row2,column1: P-R = 42-25 = 17
row2,column2: P-R = 35-(-30) = 65
row2,column3: P-R = -19-36 = -55
The values in bold correspond to the proper values shown in choice B.
As you can probably guess by now, matrix addition and subtraction is only possible if the two matrices are the same size (same number of rows, same number of columns). The matrices don't have to be square.
Answer:
n=0.3
Step-by-step explanation:
divide the numbers
0.2/n=0.4/0.6
0.2/n=.066666
then you multiply by the same dominator to both sides
n*.02/n=n*.066666
Cancel multiplied terms that are in the denominator
0

Answer:
52 Empty Seats
Step-by-step explanation:
10 rows of 8 seats would be 10 x 8, which you would get 80. Then you would subtract the amount of people seated in those seats. which is 28
10 x 8 = 80
80 - 28 = 52
There are 52 empty seats left.
The measure of angle G in terms of x is x+x degrees
<h3>Circle theorem</h3>
The measure of angle F and angle D is 90 degrees so that;
<GFD = <GDF = 90 - x
Since the sum of angle in a triangle is 180 degrees, hence;
<G + 90 - x + 90 - x = 180
<G + 180 - 2x = 180
<G = 2x
<G = x + x
Hence the measure of angle G in terms of x is x+x degrees
