The distance between (-5 , -8) and (-1 , -16) is 8.9 units ⇒ 1st answer
Step-by-step explanation:
The distance between points 
and 
is 
To find the distance between two points
- Chose one of the two point to be
- Use the other point to be
- Substitute them in the rule of the distance
∵ The first point is (-5 , -8)
∵ the second point is (-1 , -16)
∴ 
= -5 and 
= -1
∴ 
= -8 and 
= -16
- Substitute these values in the rule of the distance
∵ 
∴ 
∴ 
∴ 
∴ 
∴ d = 8.9 units
The distance between (-5 , -8) and (-1 , -16) is 8.9 units

Step-by-step explanation:
Speed of the train : distance traveled / time of the travel = 10.1/(0.5)=<span>20.2 mph. Hope this helped!</span>
If the original volumes of liquid is represented by x, we have x=x for A and B. Since 120mL is poured from A to B, A loses 120 mL (x-120) and B gains 120 mL (x+120). Since we know that B contains 4 times as much liquid as A is now (x-120), we have 4*(x-120)=(x+120)=B. Using the distributive property, we get 4x-480=x+120. Adding 480 to both sides, we get 4x=x+600. After that, we can subtract both sides by x to get 3x=600. Lastly, we can divide both sides by 3 to get x=200=the original amount of liquid. Since A=x-120, we get A=200-120=80
