You need to multiply another number each time.
For Example:
3x2=6
6x3=18
18x4=72
72x5=360
360x6= 2,160

It's a pattern

The sum of 6 consecutive integers is 387. What is the sixth number in this sequence.

11111nata11111 [884]

Answer:

67!

Step-by-step explanation:

A way to look at it is, since the number is 387, it can be broken into 6 parts. 50x6 is about 300. That leaves 87 to be left over. So it's safe to assume each number will be around 50-60, so I started to add up six consecutive numbers together until I reached my final set of numbers to reach 387.

My numbers were 62+63+64+65+66+67=387

I hope this makes sense!

Answer:

0.25

Step-by-step explanation:

1. Add up all of the students.

20+20+25+7+13+5+3+2+5=100

2. Make a ratio of that number and the number of all the students in Music/Drama

MUSIC/DRAMA: 7+13+5=25

$\frac{25}{100}$

3. Simplify

$\frac{25}{100} = \frac{5}{20} =\frac{1}{4}$ = 0.25

Solve the equation 3/4x+3-2x = -1/4+1/2x+5

elena55 [62]

Hi there! The answer is x = -1

Let's solve this equation step by step!
$\frac{3}{4} x + 3 - 2x = - \frac{1}{4} + \frac{1}{2} x + 5$

First collect terms.
$- 1 \frac{1}{4} x + 3 = \frac{1}{2} x + 4 \frac{3}{4}$

Subtract (1/2)x from both sides.
$- 1\frac{3}{4} x + 3 = 4 \frac{3}{4}$

Subtract 3 from both sides.
$- 1\frac{3}{4} x = 1 \frac{3}{4}$

And finally divide by -1 3/4
$x = \frac{7}{4} \div - \frac{7}{4} = \frac{7}{4} \times - \frac{4}{7} = - \frac{28}{28} = - 1$

Quadrilateral CAMP below is a rhombus. The length of PQ is (x + 2) units, and the length of QA is

Phoenix [80]

Q cuts the diagonal PA into 2 equal halves, since the diagonals of rhombus meet at right angles.

Step-by-step explanation:

As given by the statement in the problem,

Q may be the middle point, which cut the diagonal PA into 2 equal halves.

In rhombus, diagonals meet at right angles.

which means that PQ = QA

x+2 = 3x - 14

Grouping the terms, we will get,

3x -x = 14+ 2

2x = 16

dividing by 2 on both sides, we will get,

x = 16/2 = 8

8+2 = 3(8) - 14 = 10 = PQ or QA
