Answer: D=22
Step-by-step explanation:
this is because if multiply f by r you get D and then you do all the other rmathematics and you wind up with 22
Answer is 1/5 simplified.

Answer:
There are a total of 495 people on the train
Step-by-step explanation:
Let's identify what we know:
1) The train has 3 passenger cars
2) Each passenger car has 4 columns, and each can accommodate 40 people.
3) All three passenger cars are full, but one of them has 15 additional people standing.
We can create a formula to model the problem:
x = ((3 x 4) x 40) + 15
x = the total number of passengers!
There are a total of 180 people sitting, and 15 additional people standing in one of the passengers cars, equaling a total of 495 passengers on the train.
Answer:
y = 5x-11
Step-by-step explanation:
The slope intercept form of a line is y =mx+b where m is the slope
y = -1/5 x-3
The slope is -1/5
Lines that are perpendicular have negative reciprocal slopes
-1 /(-1/5)
-1 * -5/1
5
The slope of the line that is perpendicular is 5
y=5x+b
Using the point (4,9)
9 = 5(4)+b
9 = 20+b
9-20 =b
-11
y = 5x-11
