Question

Tolonggg jawabb yahh plisss.....
yg jawab semua ini dapet pahala :D

Answer 1

1. a. 76 = 2 (p + p - 10)

        76 = 2 (2p - 10)

     b. 76 = 2(p + p - 10)   

         76 = 2(2p - 10)   

        76 = 2(p + p - 10)   

        76 = 2(2p - 10)   

       76 = 4p - 20    

         76 + 20 = 4p        

        96    = 4p       

         96/4 = p        

         24    = p

     p = 24

    l  = 24 - 10 = 14

2. a. a + 3 (22.000 - a) = 42.000

    b. a + 3 (22.000 - a) = 42.000

        a + 66.000 - 3a     = 42.000

            a - 3a                = 42.000

              -2a                  = 42.000 - 66.000

          - 2a                     = -24.000

               a                    = -24.000/-2

               a                   = 12.000

     a = 12.000\

     b = 22.000 - 12.000

3. a. b - 4 + b = 60

           2b - 4  = 60

    b. b - 4 + b = 60

           2b - 4  = 60

              2b     = 64

                 b    = 32

  b = 32

  a = 32 - 4 = 28
