Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region. For example, this graph shows the inequality .

Im not really sure if it's correct or not.. but i think it is..
r = recycling and reuse
w= waste management
equation: 1275000 =r+w
r = 1025000
1275000 = 1025000+w
-1025000 -1025000
250000 = w
r = 1025000
w = 250000
Hello!!
Total = 3/7 + 4/5 + 2/3
= 0.428571429 + 0.8 + 0.66666667
= 199/105
= 1.89524.....
≈ 1.90 (rounded to two decimal places)
Good luck :)
Answer:
By calculating the time taken to reach we get to know that the The time taken by the other person is less than yourself
Step-by-step explanation:
Given that the other person and yourself left at the same time and the speed of the other person is 60 miles per hour and the speed of yourself is 40 miles per hour.
We know that the ![speed=\frac{distance}{time}](https://tex.z-dn.net/?f=speed%3D%5Cfrac%7Bdistance%7D%7Btime%7D)
Let the time taken to reach the destination at a distance of d by the other person is T1.
Then ![60=\frac{d}{T1}](https://tex.z-dn.net/?f=60%3D%5Cfrac%7Bd%7D%7BT1%7D)
![T1=\frac{d}{60}](https://tex.z-dn.net/?f=T1%3D%5Cfrac%7Bd%7D%7B60%7D)
Let the time taken to reach the destination at a distance of d by the yourself is T2.
Then ![40=\frac{d}{T2}](https://tex.z-dn.net/?f=40%3D%5Cfrac%7Bd%7D%7BT2%7D)
![T2=\frac{d}{40}](https://tex.z-dn.net/?f=T2%3D%5Cfrac%7Bd%7D%7B40%7D)
Now the time difference is = T2-T1 =
= ![-\frac{d}{120}](https://tex.z-dn.net/?f=-%5Cfrac%7Bd%7D%7B120%7D)
Therefore T1 > T2 which means the time taken to reach the destination by yourself is greater than that of other person .
