Answer: There are 16 vans and 36 buses and Option 'c' is correct.
Step-by-step explanation:
Since we have given that
For high school A,
Number of vans = 5
Number of buses = 3
Number of students = 188
For high school B,
Number of vans = 10
Number of buses = 5
Number of students = 340
So, Let the number of students in van be 'x'
Let the number of students in bus be 'y'.
According to question, it becomes;
So, first we do:
2(5x+3y=188)
10x+6y=376----------------(3)
So, from (2) and (3), we get that
so, put the value of y = 36 in the eq(1), we get that
Hence, there are 16 vans and 36 buses and Option 'c' is correct.
the subset of -3 and 8 is: { }, {-3}, {8}, {-3,8}, {8,-3}
In the instructions for this problem I am told to distribute -4x^2. Why?
the order of operations is the order in which to simlify
if you look inside the parenthases, all like terms have been combined so the inside of parenthasees have already been simlified
expanding the exponents won't make it any easier so we move to distriubiting (or mulitplying)
so then the next step is mulitply -4x^2 by the trinomial
<span>In
the order of operations you must do problems inside parentheses first.
Why does multiplying monomials by polynomials change this? </span>multiplying monomails by polynomials does not change this
<span>Would the answer come out different if I did the work according to the order of operations?
no because distributing first is what you should do if you follow order of operations

Answer:
400cm²
Step-by-step explanation:
the surface area of the sphere =
4/3 x The total surface area of a hemisphere
=> 4/3 x 300 = 400cm²
