Notice that x+4 is one of the denominators, and that x(x+4) is the LCD.
                      x
Thus, mult. ------- by x(x+4), obtaining  x^2.  
                    x+4
Next, mult. [ 1/x + 1/(x+4) by x(x+4), obtaining   x+4 + x = 2x+4 or 2(x+4)
                                                                x^2
Then the simplified fraction becomes  ----------
                                                              2(x+4)

Generally Brainly allows you to post only 1 or 2 questions at a time.  I will do #15 as a courtesy to you, but want you to try #16 yourself (or to post it separately).

-4, 2, 8, 14, ...  is an arithm. seq.  Every new term is equal to the previous term, plus 6:  -4+6 = 2; 2+6=8, and so on.  Thus:  first term is a = -4; common difference is d = 6

a(50) = a(1) + (50-1)(6), or   a(50) = -4 + (49)(6) = 290 (answer)

The given process is an example of a cluster system.

<h3>What is the cluster system?</h3>

The clustered systems are a combination of hardware clusters and software clusters.

The hardware clusters help in sharing of high-performance disks between the systems.

The software clusters makes all the systems work together.

Each node in the clustered systems contains the cluster software.

A cluster refers to a group of inter-connected computers where it works together to support applications and middleware (e.g. databases).

In a cluster, each & every computer is known to be a “node”.

What are the numerical measures of each angle in the diagram? 1 and 3 measure degrees. 2 and 4 measure degrees. (3x - 1)º (2x +
Tanya [424]

Answer:

Step-by-step explanation:

In the diagram shown, the measure of angle 1 is oppositely directed to angle 2 and oppositely directed angles are equal.

Hence <1 = <3

Given < 1 = 3x-1 and <3 = 2x+9

Hence 3x-1 =  2x+9

collect like terms

3x-2x = 9+1

x = 10°

Since <1 = 3x-1

on substituting x = 10

<1 = 3(10)-1

<1 = 30-1

<1 = 29°

<1+<2 = 180 (angle on a straight line)

29+<2 = 180

<2 = 180-29

<2 = 151°

Similarly, on substituting x = 10 into <3

<3 = 2x+9

<3 = 2(10)+9

<3 = 20+9

<3 = 29°

<3+<4 = 180 (angle on a straight line)

29+<4 = 180

<4 = 180-29

<4 = 151°

Why is the total cost of fuel when a driver averages 8 miles per gallon..The cost of fuel is .83 cents a gallon..The drivers dis
Allushta [10]

Answer:

The total cost of the petrol is 2.075 cents.

Step-by-step explanation:

The cost of per gallon petrol = 0.83

Drive per gallon = 8 miles

Here, total distance traveled = 20 miles.

So, the total petrol used for 20 miles = (20 / 8) gallons

= 2.5 gallons

Now, cost of petrol per gallon = 0.83 cents

So, total cost of petrol = 0.83 x 2.5  = 2.075 cents

Hence, the total cost of the petrol is 2.075 cents.
