You went on three hikes. on each hike, you saw a different number of animals: hike length of hike (\text{km})(km)left parenthesis, start text, k, m, end text, right parenthesis number of animals seen rivers edge 3 8 wooded marsh 8 20 canyon creek 15 35 order your hikes by number of animals seen per kilometer from least to greatest

Canyon Creek - Wooded Marsh - Rivers Edge

Step-by-step explanation:

The hiker saw 8 animals in 3 km in Rivers Edge, that makes 8/3 = 2.67 animals per kilometer.

The hiker saw 20 animals in 8 km in Wooded Marsh, that makes 20/8 = 2.5 animals per kilometer.

The hiker saw 35 animals in 15 km in Canyon Creek, that makes 35/15 = 2.33 animals per kilometer.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

6/20
