Please Help Work Due Tmrw And Im Stuck On The First Half class=

Sagot :

Answer: 9. x=4    ST=11

             10. x=17  UW=67

Step-by-step explanation:

9.

[tex]RS+ST=RT\\RS=6x+1\ \ \ \ \ ST=x+7\ \ \ \ RT=36\\Hence,\\6x+1+x+7=36\\7x+8=36\\7x+8-8=36-8\\7x=28\\[/tex]

Divide both parts of the equation by 7:

[tex]x=4\\ST=x+7\\ST=4+7\\ST=11[/tex]

10.

[tex]UV+VW=UW\\UV=19\ \ \ \ UW=4x-20\ \ \ \ UW=6x-35\\Hence,\\19+4x-20=6x-35\\4x-1=6x-35\\4x-1-4x=6x-35-4x\\-1=2x-35\\-1+35=2x-35+35\\34=2x[/tex]

Divide both parts of the equation by 2:

[tex]17=x\\UW=6x-36\\UW=6*17-35\\UW=102-35\\UW=67[/tex]
