23
because
the pattern is
(5 10) ..1.. (15 20) ..2.. (25 30) ..3..


..1... = 3
..2.. = 13
so ..3.. = 23

Answer:

23

Step-by-step explanation:

The given series of numbers is 5 10 3 15 20 13 25 30 _

Segregating the numbers in sets of 3 we have:

5 10 3

15 20 13

25 30 _

The difference between 2 corresponding terms in adjacent sets is 10.

For example: taking the first terms from each set,it is 5, 15 , 25

Similarly taking the second term from each set, it is 10,20,30

Hence, taking the third term: 3, 13, 23.

So the missing term in the sequence is 23.

2.There is this theorem stating that the length of the altitude drawn to the hypotenuse of a right triangle is the geometric mean between the segments that the hypotenuse is divided into. In numerical form it would look like this:

6/altitude = altitude/x-6

We can solve the length of the altitude by using Pythagorean Theorem. The altitude creates two triangles within the large triangle. We will be using 6 and 10 to find the altitude. Fortunately, instead of squaring the sides we can simply use the common triple: 3,4,5 to deduce that the length of the altitude is 8. 

Now that we have the value for the altitude we can substitute it into the equation above.

6/8=8/x-6
Cross multiply
64 = 6x - 36
Add 36 to both sides
100 = 6x
50=3x
50/3=x

13. There is another theorem that <span>an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle. In numerical form it would look like this:
20/x = 12/6
cross multiply
12x = 120
x=10</span>

Subtract the average from the sales to get the deviation.

Aug. 1700 - 1412.50 = 287.50

Sept. 1125 - 1412.50 = -287.50

Oct. 1850 - 1412.50 = 437.50

Nov. 1500 - 1412.50 = 87.50

Dec. 1050 - 1412.50 = -362.50

If you were to solve the system using the addition method, what would you multiply the first equation by in order to make the x'
Inessa05 [86]
2 times 2=4
multiply first equation by 2 to get
-4x+6y=12
then add to get

-4x+6y=12
<u>4x-2y=8 +</u>
0x+4y=20

4y=20
y=5

sub back
-2x+3y=6
-2x+3(5)=6
-2x+15=6
-2x=-9
x=9/2=4.5


the number to multiply by is 2
