Step-by-step explanation:
Start at one end of the 50-foot line segment.
At position 0 ft, put one tree.
Then 1 ft from 0 ft, put tree number 2.

Answer:
The percent
Step-by-step explanation:
She got a 9% grade
and there asking you
the number of points
might be wrong but :)
Total was 200
x+y=200
biking was 40 mor than bus
x=40+y
subsitute 40+y for x in other equation
x+y=200
40+y+y=200
40+2y=200
minus 40 both sides
2y=160
divide both sides by 2
y=80
sub back
x=40+y
x=40+80
x=120
120km biked
80km on bus
