Team a has 42 members. team b has 18 more members than team a. what percent of the members from team b must be transferred to team a so that team a has as many members as team b?

15 %

Step-by-step explanation:

            42 = members of team A

            60 = members of team B

        Let x = percent of members transferred

0.01x × 60 = 0.6x = no of members transferred

 60 - 0.6x = 42 + 0.6x

           60 = 42 + 1.2x

            18 = 1.2x

              x = 15

15 % of the members on Team B must be transferred to Team A.

Check:

60 - 0.6 × 15 = 42 + 0.6 × 15

            60 - 9 = 42 + 9

                  51 = 51

OK.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
