Answer:
The distance cover by him walking back is 11.25 miles
Step-by-step explanation:
Given as :
Time for Janelle to spend on training = 5 hours
The running speed of Janelle = 9 mph
The walking back with 3 mph
Let The distance for running and walking is same i.e D miles
SO, Time = 
∴ 5 = 
+ 
Or, 5 × 9 = D + 3 D
Or, 45 = 4 D
∴ D = 
= 11.25 miles
Hence The distance cover by him walking back is 11.25 miles Answer
28 / 7 = 4
3 x 4 = 12
It’ll take him 12 minutes
Step-by-step explanation:
let eqn be y = mx + b.
m = (5 - (-11))/(0 - 4) = -4
sub (0, 5):
5 = -4(0) + b
b = 5
therefore, eqn is y = -4x + 5

Answer:
2x + y = 16
Step-by-step explanation:
In rectangle side AB and side CD are parallel, so the slope of both the lines will be same it means that they are parallel to each other.
slope of line AB:
slope of line CD = slope of line AB = -2
∴ equation of line CD:
