Using the combination formula, it is found that the number of ways to choose the presenters is given by:
C. 462.
The order in which the presents are chosen is not important, hence the <em>combination formula</em> is used to solve this question.
<h3>What is the combination formula?</h3>
 is the number of different combinations of x objects from a set of n elements, given by:
 is the number of different combinations of x objects from a set of n elements, given by:

x = 3/2
Step-by-step explanation:
Given equation is:

As we have to solve for x, x will be isolated on one side of the equation
So,
<u>1. Addition property of equality </u>
4x will be added on both sides

<u>2. Division property of Equality</u>
Dividing both sides by 6

Hence,
x = 3/2

Answer: Nicole has 88 erasers in all
Step-by-step explanation:
Number of erasers that Nicole has = 83
 Number of erasers given to Nicole= 5
 Total number of erasers Nicole has in all = 83+5= 88 erasers
 Therefore Nicole has 88 erasers. 
 
        
             
        
        
        
Answer:
About Points
S = (x,y)        searched point (it will be in the third quadrant )
M = (-2,0)      Midpoint | SP |
P = (3,5)        one end of the segment | SP |
You have to draw Cartesian.
 we set in a point M and P. We both points by a simple and we extend it for the third quarter of the system. Compass measure the distance from the point M to the point P. From the point M we set a compass point S. Figure attached. Received point S = ( -7 , -5 ) . It sought a point that calculate .
We use the information that | SM | = | MP |
Answer : S = (-7,-5)
Step-by-step explanation:
