2. In a school of 320 students, 85 students are in the band, 200 students are on sports teams, and 60 students
Alja [10]

Answer:

<u>60</u> students are involved in either band or sports.

<u>95</u> students  are not involved in either sports or band.

Step-by-step explanation:

Given:

In a school of 320 students, 85 students are in the band, 200 students are on sports teams, and 60 students  participate in both activities.

Now, to find the students  are involved in either sports or band. And students who are not involved in either sports or band.

<em>Total number of students</em> = 320.

Number of students in the band = 85.

Number of students in the sports team = 200.

Number of students participate in both activities = 60.

Thus, 60 students are involved in either band or sports.

So, the number of students in the band adding number of students in the sports team we get:

200 + 85 = 285.

Then, to subtract the number of students participate in both activities we get:

285 - 60 = 225.

<em>Thus, the remaining students are </em>= 225.

Now, to get the students  who are not involved in either sports or band we subtract the total number of students from the remaining students:

320-225

=95.

Therefore, 60 students are not involved in either band or sports. 95 students  are not involved in either sports or band.

Two buses leave towns 520 kilometers apart at the same time and travel toward each other. One bus travels 16 km/h slower than th
vampirchik [111]

Answer:

122 km/h

138 km/h

Step-by-step explanation:

distance = speed * time

One bus travels 16 km/h slower than the other

(s * 2)  + (s - 16)2 = 520

2s + 2s - 32 = 520

4s = 552

s = 552/4

s = 138 km/h

s - 16 = 122 km/h
