This is a concept of combination, the question requires us to find out how many combinations of students a teacher can choose if she sends 3 of her student to pick up books for the class. Since there is no specific order in selection, the combination will be given by:
nCr
n=Total number of the sample
r=number of students o be selected
thus the combination will be:
18C3
=816
This implies that there are 816 ways in which the Ms Washington can select the students

How can you use a number line to model and compare positive and negative rational numbers
kifflom [539]
Hello There!

Well, as you know a number line is a line where you can place numbers with different spaces between them. It can be used to compare them in distance (the further apart they are on the line, the greater the difference between the two numbers)

Hope This Helps You!
Good Luck :)

(08.06 MC) Carly and Janiya put some money into their money boxes every week. The amounts of money (y), in dollars, in their mon
Pavel [41]
For this case we have the following equations:
 y = 60x + 40
 y = 50x + 80
 Equaling both equations we have:
 60x + 40 = 50x + 80
 From here, we clear the value of x:
 60x - 50x = 80 - 40
 10x = 40
 x = 40/10
 x = 4 weeks
 Substituting x = 4 in any of the equations we have:
 y = 60 (4) + 40
 y = 240 + 40
 y = 280 $
 Answer:
 
$ 280 4 weeks

Maria sold 20 shares of stock for a total of $2980. what was the value of one share?
belka [17]
Nice and simple. I'll explain it to you, not just give the answer.

Now, 20 shares = 2980, lets make shares = x, which means it turns to

20x = $2980

Now, you'd simply solve for X, which is done by dividing 2980 by 20, which gets you
 
x = 149 (cost of one share)
