Answer:
Step-by-step explanation:
The first choice is correct
The rate is 20 per dog, thus we get the equation:
c= 20d
However the first dog is free, so the equation becomes
c = 20(d - 1)
And he also has a walking fee of 85 dollars and thus the equation becomes
c= 85 + 20(d-1)
Hi!
If the perimeter of the triangle is 41, then x is:
5x + 2 + 6x - 3 + 3x = 41
5x + 6x + 3x = 41 + 3 - 2
14x = 42
x = 42/14
x = 3
The x is 3.
