Step-by-step explanation:
We are given the following information in the question:
Total number of students in school = 240
Number of students that play soccer =

n(S) =80

Formula:

Putting the values, we get,

Thus, 144 students play basketball.
Out of these 144, 44 plays soccer as well.

Thus, 100 students play only basketball and not soccer.
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
6 lessons per week multiplied by the number of weeks in a year
6 x 52 = 312
total - 5 missed
