4,6,8 are being counted by twos so the next one is 10
4•3= 12, 6+3=9, 8-3=6, the next operation I assume would be division so 10/3= 3.34

<h2>Answer:</h2>

The next number in the series will be:

                            10

<h2>Step-by-step explanation:</h2>

We are given a series by:

            4     12     6     9     8     6

By looking at the series we observe that the series is operated by two operations alternatively.

The odd term of the series i.e. 1st term, 3rd term , 5th term and so on are obtained by adding 2 to each of the preceding term .

and the even term of the series i.e. 2nd term, 4th term, 6th term , 8th term and so on are obtained by subtracting 3 to each of the preceding term.

i.e.  odd series is:

4+2=6

6+2=8

8+2=10

even term of the series:

12-3=9

9-3=6

                 Hence, the answer is:  10

Which equation represents a line which is parallel to the line 3x - y = 6?​
DochEvi [55]

Step-by-step explanation:

We just have to remember the line equation <u>y=mx+b</u> , then place the given equation into this form (y= -3x-6).

Remember that (m) is your slope. So, to find a parallel line, they must have an equal slope. Check the other equations and see which one had a slope of -3. The answer C also has a slope of -3. So those lines would be parallel.

Answer:

The number of visit so that both plan cost same is 10 .

Both the plan has equivalent choice of benefit

Step-by-step explanation:

Given as :

A gym has two membership plans.

For Gold plan

The charge per month = $50  

The charge per visit = $3

For Platinum plan

The charge per month = $20  

The charge per visit = $6

Let The number of visit for which each plan be same = n visits

Now, According to question

<u>∵ Each plan cost to be same</u>

So,

The charge per month for gold plan+ The charge per visit × numbers of visit = The charge per month for platinum plan+ The charge per visit × numbers of visit

I.e $50 + $3 × n = $20 + $6 × n

Or, $50 - $20 =  $6 × n  -  $3 × n

Or, $30 = ($6 - $3) × n  

Or, $30 = $3 × n  

∴ n = \dfrac{30}{3}

I.e n = 10

So, The number of visits = n = 10

Now, For Gold plan

The charge per month = $50  

The charge per visit = $3 × 10 = $30

So, Total charge for gold plan = $50 + $30 = $80

Similarly For Platinum plan

The charge per month = $20  

The charge per visit = $6×10 = $60

So, For Platinum plan ,total charge = $20 + $60 = $80

Hence, The number of visit so that both plan cost same is 10

and both the plan has equivalent benefit. Answer
