Question

its about geometry i need help its urgent

Answer 1

Answer:

1) 37

2) 23

3) x = 4

4) 58

Step-by-step explanation:

1) 15 + 22 = 37

2) 54 - 31 = 23

3) 6x + 1 + x + 7 = 36

7x + 8 = 36

7x = 28

x = 4

4) 3x + 10 + 47 = 9x - 39

57 = 6x -39

96 = 6x

16 = x

3(16) + 10 = 58

Answer 2

Answer:

see below

Step-by-step explanation:

             22                15

1.  L -----------------M------------N          LN = 22 + 15              LN = 37

   

             31                ??

2.  L -----------------M------------N          MN = 54 - 31            MN = 23

     |<-----------54 ---------------->|

             6X+1             X+7

3.  R -----------------S------------T          find X

      (6x + 1) + (x + 7) = 0

       7x = -8

        x = - 8/7

          47              3X+10

4.  D -----------E---------------------F          find EF

     |<--------- 9X - 39 ------------>|    

    47 + (3x + 10) = (9x - 39)

    3x - 9x = -39 - 10 -47

    -6x = -96

     x = -96 / -6

     x = 16

    EF = 3x + 10

    EF = 3(16) + 10

    EF = 58
