7/x+1=2x-1/36 solve for x
tia_tia [17]

Answer:

x = 11 is the solution of a given algebraic expression

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given

        \frac{7}{x+1} = \frac{2x-1}{36}

cross multiplication, we get

    7 ( 36) = (2x -1) (x +1)

   252    =  2 x ( x +1) -1( x+1)

  252    = 2 x² + 2x - x -1

  252    = 2 x² + x -1

  2 x² + x -1 = 252

  2 x² + x  = 252 +1

  2 x² + x - 253 = 0

<u><em>Step(ii)</em></u>:-

The factors of 2 x² + x - 253 = 0

  2 x² + 23 x - 22x - 253 =0

  x ( 2x + 23) - 11 ( 2x +23 ) =0

  ( x -11) ( 2x + 23) =0

  x = 11  ,  x = \frac{-23}{11}

<u><em>Final answer:</em></u>-

The value of x = 11

lana [24]
There are several information's that are given in the question. Based on these information's the answer can be easily deduced.

Amount of water that <span>Mariana's swimming pool holds = 22000 gallons
7.5 gallons = 1 cubic feet
Then
22000 gallons = 22000/7.5 cubic feet
                        = 2933 cubic feet
From the above deduction, we can conclude that the correct option among all the options that are given in the question is the second option or option "B".</span>

For the following​ case, assume that the population standard deviation is known and decide whether use of the​ z-interval proced
Ray Of Light [21]

Answer:

B. It is reasonable to use the? z-interval procedure in this case? since, although the sample is small? (size less than? 15), the variable under consideration is very close to being normally distributed.

Step-by-step explanation:

answer b is considered to be correct because we know that the population is normal and the standard deviation is known, which allows using the interval z, the answer A is not correct because although the option to use the interval z is given, which is correct, the large sample is not favored, the answer C and D are incorrect because they both reject the use of the z interval and in d it is further rejected that although there is a normal distribution the sample is not, which is false
