Ray AB and ray BC are _____ on the same line

2 answers:

8 0

I would say that they are sometimes on the same line. Think of the following scenario: a line, AC, is bisected by point B. You do indeed have two rays, each representing a part of the line.

Another scenario, think of a standard number line. Say AB goes from -1 to -3 and then continues to the left. BC goes from 2 to 4 and then continues to the right. These are two rays, each pointed in opposite directions, but on the same line.

C. Never

This is because they should be parallel if the are two separate rays.

How do you solve this ???

galina1969 [7]

First you have to figure out how much a video game costs and how much a used one costs
Then you plug in the costs of the video games into Janets equation 120=3x+y
(x= video games and y=used video games)
Then you subtract the cost of video games from 120 and then divide that answer by the cost of used video games and that should give you how many used video games she can get

Alvin wants to know what his average paddling rate was for a canoe trip to a campsite. On the way there it took him 8 hours agai

Marizza181 [45]

let

r--------> Alvin's average paddling rate in km/hour

y -------> speed of the current in km/hour

we know that

speed= distance/time ------> solve for distance

distance=speed*time

to Campsite against the current

speed=r-y-----> speed=(r-3)

time=8 hours

distance=(r-3)*8------> equation 2

From Campsite with the current

speed=r+y-----> speed=(r+3)

time=3 hours

distance=(r+3)*3------> equation 1

equate equation 1 and equation 2-----> because is the same distance

(r+3)*3=(r-3)*8----> 3r+9=8r-24----> 8r-3r=24+9-----> 5r=33----> r=6.6 km/hour

therefore

the answer is

Alvin's average paddling rate is 6.6 km/hour

3 times the sum of 1/3 of<br> a number and 8 is 11

Anni [7]

Answer:

I guess this is how to do it....

3×(1/3 of x + 8)=11.

use the 3 to multiply the numbers in the bracket.

3x+24=11.

3x=11-24.

3x=-13.

x= -13/3.

x= -4.33.
