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.

Answer: A & C
The dimensions of the larger cylinder are 3 times the dimensions of the smaller cylinder.
If proportional dimensional changes are made to a solid figure, then the surface area will change by the square of the scale factor of similar solids.
Step-by-step explanation:
(a) y = -7/5x + 17.8
(b) it decreased by 7/5 per day.
Hope this helps!!! :)
The correct answer is G. y=15x+80 because y represents the total, 15x represents the number of months times 15 because it increases by 15 members every month. And then you started with 80, so there's plus 80 at the end.
