Let x be the number of students in Emily's class such that 75% of x is 15. 
                                        15 = 0.75x
The value of x is equal to 20.  
Let y be the number of students in Santiago's class. Similar with what we did previously,
                                          12 = (2/3)y
The value of y is equal to 18. 
Therefore, there are more student's in Emily's class than in Santiago's class.

LAST QUESTION ON MY TEST PLEASE HELP
Kipish [7]

Answer:

x = 8

Step-by-step explanation:

For this question, you can use power of a point, more specifically when two secants intersect in the interior of a circle. From this, you get the equation:

(7 + x)(12) = (10)(2x + 2)

You can simplify and solve:

84 + 12x = 20x + 20

84 = 8x + 20

64 = 8x

x = 8
