Hello from MrBillDoesMath!
Answer:
5, 10, 0
Discussion:
Let "f" be the first number. Then the questions tells us that
f + 2f + (f-5) = 15 =>
f + 2f + f - 5 = 15 => add 5 to both sides
4f = 5+ 15 = 20 => divide both sides by 4
f = 20/4 = 5
The numbers as
f: 5
2f: 10
(f-5): 0
Thank you,

Answer:
the slope is 0.75
Step-by-step explanation:
you have to find the coordinate of each point then put them in acording to the formula in this case the coordinates are (-2,3) X1 and X2 and (-1,1)y1 and y2
It takes 15 minutes for Ms. Peter to drive from park to her home
Given :
from her home to the park at an average speed of 30 miles per hour and
returned home along the same route at an average speed of 40 miles per hour
it takes 20 minutes to travel
Convert 20 minutes in to hour (divide by 60)
20 minutes = 1/3 hour
We know that distance = speed x time
From home to park, distance =![speed \cdot time =30 \cdot \frac{1}{3} =10 miles](https://tex.z-dn.net/?f=speed%20%5Ccdot%20time%20%3D30%20%5Ccdot%20%5Cfrac%7B1%7D%7B3%7D%20%3D10%20miles)
So , distance between home and park is 10 miles
Now we calculate the time taken to return from park to home
![time taken =\frac{distance}{speed} =\frac{10}{40}=\frac{1}{4}\\](https://tex.z-dn.net/?f=time%20taken%20%3D%5Cfrac%7Bdistance%7D%7Bspeed%7D%20%3D%5Cfrac%7B10%7D%7B40%7D%3D%5Cfrac%7B1%7D%7B4%7D%5C%5C)
Time taken is 1/4 hours. Convert it into minutes by multiplying by 60
![\frac{1}{4} \cdot 60=15](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%5Ccdot%2060%3D15)
So it takes 15 minutes for Ms. Peter to drive from park to her home

Yes it is because 4+4=8 and 8 is larger than 7
