1.) 7+7/9x=−42 2.) 4x+1=−15 3.)−4(x−3)=−40
Over [174]

Answer:

1) x= -1/27

2) x=-4

3) x=13

Step-by-step explanation:

1) 7+7/9x= = -42

   14/9x= = -42

  14/9x X 9x= -42 X 9x

    14= -378x

    -378x= 14

   -378x/-378= 14/-378

      x= -1/27

2) 4x+1=−15

 4x+1-1=-15-1

    4x=-16

   4x/4= -16/4

      x=-4

3) −4(x−3)=−40

 -4(x-3)/-4= -40/4

     x-3=10

   x-3+3=10+3

        x=13

Suppose △PKN≅△BGH.
OLga [1]

Answer:

△KNP ≅ △GHB

△NPK ≅ △HBG

Step-by-step explanation:

Given: △PKN≅△BGH

This means two triangles PKN and BGH are congruent. Congruent triangles havecongruent  corresponding parts.

So,

  • PK ≅ BG;
  • PN ≅ BH;
  • KN ≅ GH;

and corresponding vertices

  • P to B;
  • K to G;
  • N to H.

Hence,

A. Triangle KNP is congruent to triangle GHB - true

B. Triangle KPN is congruent to triangle GBH - false

C. Triangle NKP is congruent to triangle HGB - false

D. Triangle NPK is congruent to triangle HBG - true
