If I understand this problem correctly the answer would be 29 more people can board the plane! Hope this helps! Comment if you have questions!!!
Answer:
(a) x=−20 1/2
Step-by-step explanation:
Multiply by the product of the denominators and solve the resulting linear equation in the usual way.

Step-by-step explanation: look so if you have
shcool A its 8v+4b=12
and
School B: 12v+4b= 16
since both classes used 4 busses we can use elimination by subtracting the A class Equation from the b class equation to solve from v for its value Then, use either equation and the now found value for v to solve for b.
You should find part of the process to be
12v+4b-(8v+4b)=12-16 which shows the van holds only a few people even before continuing the solution.
Answer -4
This is volume of a sphere.
R(x) is a polynomial. Thus, the domain is the same as the range.
Domain = range = ALL REAL NUMBERS.
We can also express the answer as
(-infinity, infinity).
