Answer: There are 18 students in a van and 24 students in a bus.
Step-by-step explanation:
Let the number of students in the van be 'x' and the number of students in bus be 'y'.
Then, According to the question, we have the following system
![\text{[High School A ]}\ x+10y=258........................(1)\\\\\text{[High School B ]}\ 8x+5y=264........................................(2)\\](https://tex.z-dn.net/?f=%5Ctext%7B%5BHigh%20School%20A%20%5D%7D%5C%20x%2B10y%3D258........................%281%29%5C%5C%5C%5C%5Ctext%7B%5BHigh%20School%20B%20%5D%7D%5C%208x%2B5y%3D264........................................%282%29%5C%5C)
Multiply 2 to both the sides of equation (2), we get

Subtract equation (1) from equation (3), we get

Substitute value of x in (1), we get

Hence, there are 18 students in a van and 24 students in a bus.
The answer to this would be 3/8.
you just simplify the given terms, so -1 7/8 can be simplified into -15/8 and 2 1/4 can be simplified into 9/4, add those together to get a sum of 3 over 8 or 3/8.
Good Luck
Answer:
50
Step-by-step explanation:
The sum of the angles of a triangle is 180
A +B +C = 180
90 +4x+ 7x-20 =180
Combine like terms
70+ 11x = 180
Subtract 70 from each side
70-70+11x = 180-70
11x=110
Divide each side by 11
11x/11= 110/11
x = 10
We want to find angle C
C = 7x-20
= 7*10-20
= 70-20
= 50
