Answer:

The next number to complete the sequence is 13

Step-by-step explanation:

The sequence of given data is the reducing number by the specific value and the add double of same number in the outcome.

The difference between numbers

-6-3 = -9

12 -(-6) = 18

4 - 12 = -8

20 - 4 = 16

The pattern if behaves as

x-n

x-2x

According to given pattern new number should be

x - 20 = -7

x = -7 +20

x = 13

The next umber will be 13

Answer:

13

Step-by-step explanation:

From the sequence above the number has a negative sign,increasing and decreasing at rates not quite understandable unless a proper attention is paid.

The sequence of the above data is the reducing number by the specific value and the add double of same number in the outcome.

Take a look a this

-6-3 = -9(the first number is subtracted from the second)

12-(-6)=18

4 - 12 = -8

20 - 4 = 16

From the above one can realize that the outcome of every single linear algebra having the -ve sign will increase by 1(that means +1 is added to the previous number with a negative sign.

So to following the sequence, the next number will b -7

According to given pattern new number should be

x - 20 = -7

x = -7 +20

x = 13

Delvig [45]

Answer:The equation that models the solution will be

33 = 22k / 6

Step-by-step explanation:

The two types of variation involved in this problem are direct variation and inverse variation.

In direct variation, when one item changes in the positive or negative direction, the other item also changes in the positive or negative direction.

In inverse variation, when one item changes in the positive or negative direction, the other item also changes in the negative or positive direction.

From the information given,

c varies directly with b

If we introduce a direct proportionality constant, k, then,

c = kb

c also varies inversely with a

If we introduce an inverse proportionality constant, k, then,

c = k/b

Therefore, c = kb / a

When a=6 , b=22 and c=33.

The equation that models the solution will be

33 = 22k / 6

An isosceles triangle has a vertical angle of 108 and a base 20 cm long. Solve for the base angles in calculated altitude.
xeze [42]

Answer:

The base angles are 36° each

Step-by-step explanation:

An isosceles triangle is a triangle that has two of its sides and base angles to be equal.

If an isosceles triangle has a vertical angle of 108°, then the base angles will share the remaining angle in the triangle equally.

Since the sum of angles in a triangle is 180°

The remaining angle in the triangle = 180°-108°

= 72°

Since the base angles are equal, this remaining two angles will share angle 72° equally.

The base angles = 72°/2

The base angles = 36°

This shows that the base angles are 36° each.

Quadrilateral DEFG - quadrilateral KLMN. Find the given side length.
Delvig [45]

Answer:

Step-by-step explanation:

By the diagram FG = MN.

3y + 3 = 5y - 25          Add 25 to both sides

3y + 3 + 25 = 5y         Subtract 3y from both sides

28 = 5y - 3y                Combine

28 = 2y                       Divide by 2

28/2 = 2y/2

y = 15

15 is not your answer. It is just the value of y.

3y + 3 = 3*15 + 3 = 45 + 3 = 48
