Answer:
The number of students in each <u>van are 7</u> and number of students in each <u>bus are 23.</u>
Step-by-step explanation:
Let the number of students in each van be 'x' and number of students in each bus be 'y'.
Given:
<u>High School A:</u>
Number of students = 132
Number of buses = 3
Number of vans = 9
As per question,
-------1
<u>High School B:</u>
Number of students = 205
Number of buses = 8
Number of vans = 3
As per question,
-------2
Multiplying equation (2) by -3 and adding the result to equation (1), we get:
Now, plug in 23 for 'y' in equation (1) and solve for 'x'. This gives,
Therefore, the number of students in each van are 7 and number of students in each bus are 23

Answer:
4
Step-by-step explanation:
180= ((14+b)20)/ 2
(2)180=((14+b)20)2
360=(14+b)20
360/20=(14+b)/20
18=14+b
4=b
x + y = 21
x + y - 8 = 3*y + 5
Subtract y from both sides.
x - 8 = 3y - y + 5
x - 8 = 2y + 5 Substitute x = 21 - y into the equation
21 - y - 8= 2y + 5
13 = 3y + 5 Subtract 5 from both sides
13 - 5 = 3y
8 = 3y Divide by 3
y = 8/3
x + y = 21
x + 8/3 = 21
x = 21 - 8/3
x = 18 1/3 or 18.333333
Check
The smaller number is 8/3
x + y - 8 = 3*(8/3) + 5 Remember that x + y = 21
21 - 8 = 8 + 5
13 = 13 and they check. Which one is the smaller number does not become a factor until you check your answer.
