its k=2

One solution was found :

                  k = 2

Step by step solution :

Step  1  :

           1

Simplify   —

           3

Equation at the end of step  1  :

       2          1      

 ((k • —) +  (k • —)) -  2  = 0

       3          3      

Step  2  :

           2

Simplify   —

           3

Equation at the end of step  2  :

       2     k    

 ((k • —) +  —) -  2  = 0

       3     3    

Step  3  :

Adding fractions which have a common denominator :

    Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2k + k     3k

——————  =  ——

  3        3

Reducing to Lowest Terms :

   The above result can still be reduced :

    3k    

    —— = k

    3      

Equation at the end of step  3  :

 k -  2  = 0

Step  4  :

Equation at the end of step  4  :

 k - 2  = 0

Step  5  :

Solving a Single Variable Equation :

  Solve  :    k-2 = 0

Add  2  to both sides of the equation :

                     k = 2

One solution was found :

                  k = 2

Step-by-step explanation:

Consider x⅓ =a

then the following expression can be written as

a²+a-2

a²+2a-a-2

a(a+2)-1(a+2)

(a+2)(a-1)

a= -2 or, a= 1

Putting the value of a

x⅓ = -2 and, x⅓ =1

zzz [600]

Answer: f(y) x g(y) = 1

Step-by-step explanation:

\frac{2y^3-y^2+2y-1}{y^3-y^2+y-1}\cdot \frac{2y^2-3y+1}{4y^2-4y+1}\\\\= \frac{4y^5-8y^4+9y^3-9y^2+5y-1}{4y^5-8y^4+9y^3-9y^2+5y-1} \\\\= \frac{(y-1)(2y-1)(2y-1)(y^2+1)}{(y-1)(2y-1)(2y-1)(y^2+1)} \\\\= 1

the ratio of adults to children attending a new exhibit st the museum was found to be 8:5. Based on this ratio if 390 people att
Natali5045456 [20]
First, you add the two parts of the ratio together. 8+5=13. Then you do 390 divided by 13 which is 30. After this, you multiply 30 by each side to get the ratio to be equal. 30x8=240, and 30x5=150. This can now be put into the ratio 240:150. As you said it was in the ratio adults to children, it must stay in that order. The part of the ratio for children is 150. 
<em>The answer to your question is 150. You can double-check your answer by adding up the two parts again. 240=150=390 so you can be assured that your answer is truly correct. Thank you for uploading this question. I hope my explanation was helpful enough for you
