Answer:
r = (x - 10m)/w
Step-by-step explanation:
Isolate the variable, r. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 10m from both sides of the equation:
rw + 10m (-10m) = x (-10m)
rw = x - 10m
Next, divide w from both sides:
(rw)/w = (x - 10m)/w
r = (x - 10m)/w
r = (x - 10m)/w is your answer.

Answer:
The problem with this question is that it is missing an important number, which is the length of the tube. Assuming that the tube is 10 meters long (=1,000 centimeters long)
time (in distance traveled distance traveled distance
seconds) by particle A in cms by particle B in cms between both
particles in cms
1 97 49 854
2 93 47 714
3 89 45 580
4 85 43 452
5 81 41 330
6 77 39 214
7 73 37 104
8 69 35 0
After 8 seconds both particles should meet. Particle A traveled 664 centimeters and particle B traveled 336 centimeters.
<h3><u>MEAN</u></h3>
Mean is the average. To find the mean of a data set, you have to add all the numbers and divide the sum by the amount of numbers you added.
<em>In this equation, you have 8 numbers. That means you will be dividing by 8. </em>
The first thing you need to do is add all the numbers. Add:
Now that you have added all the numbers and got the sum, divide by 8. Remember that you will be dividing by 8 since you added 8 numbers.
Divide:
The mean is 66

Add up the lunch and belt.
5.47+8.95
14.42
Now subtract that from the money Jane had at first.
23-14.42
8.58
So B. Jane has spent $8.58 on the necklace.
