The van can carry 6 students and bus can carry 21 students.

Step-by-step explanation:

Given,

High School A: 12 vans and 11 buses with 303 students

High School B: 6 vans and 7 buses with 183 students

To find the number of students that a van and a bus can carry.

Let us take,

The van can carry x students and the bus can carry y students.

According to the problem,

12x+11y = 303 ------- (1)

6x+7y = 183 ------- (2)

Multiplying 2 with (2) and subtract (1) and (2) we get,

(12x+11y) - 2(6x+7y) = 303-2(183)

or, 12x+11y-12x-14y = 303-366

or, -3y = -63

or, y = 21

From (2) we get,

6x+7(21) = 183

or, 6x = 183-147

or, 6x = 36

or, x = 6

Hence,

The van can carry 6 students and bus can carry 21 students.

Find the value of x and y
Yakvenalex [24]

Answer:

x = 80, y = 122

Step-by-step explanation:

I got this equation by using vertical angles to create a complimentary angle pair (they sum to 90 degrees).

3/4x+2/5x-2=90°,

23/20x - 2=90°,

23/20x = 92°,

92/(23/20)

20/(1/4)

20(4)

= 80.

Since the angles are a linear pair on the left side(they sum to 180 degrees). Just subtract 180 from 3/4x-2 and substitute x into the expression.

180-(3/4(x)-2), 180-3/4(80)+2 = 120+2 = 122

True. When the points are plotted on a graph and connected, they pass the vertical line test. No x value is the same.
