We have been given that the scale on a trail map is 0.5 cm : 1 km. The straight distance between 2 huts on the trail is 16.9 cm. We are asked to find the actual distance between 2 huts.
We will use proportions to solve our given problem.





Therefore, the actual distance between both huts is 33.8 km.
A relationship is proportional if they represent the same kind of relationship.
One way to tell if it is proportioned is to write them as fractions and then reduce them. If the reduced fractions are the same, the relationship is proportional.
Answer:
t=-3
because if you multiply -7 by 3 and then subtract, you will get 20
F(x)=x/(3x+2)
f(a+h)=(a+h)/(3a+3h+2)
