Answer:

Step-by-step explanation:

Equation

12x + (8x + 5) + 15x = 180    All triangles have 180o for their interior angles.

12x + 8x + 5 + 15x = 180      Combine like terms on the left

35x + 5 = 180                        Subtract 5 from both sides

     <u>  - 5      -5</u>

35x =175                                Divide by 35

x = 5

It's not clear what you want. x = 5 is one possibility

12x = 60

15x = 75

8x+5=45

is another possiblity

If it takes Tim 2 hours to drive to the campground and it takes 3 times more long then driving to the campground. Then all you have to do is 3 multiplied by 2 and then your answer would be 6 hours.

Hope it helps!
