The van can carry 18 students and bus can carry 21 students.
Solution:
Given that,
Senior class at high school "a" rented and filled 9 vans and 5 buses with 267 students.
High school "b" rented and filled 10 vans and 10 buses with 390 students.
Each van and each bus carried the same number of students.
Let the capacity of van be "m", and capacity of bus be "n"
Then, according to given information,
For school a ⇒ 9m + 5n = 267 ⇒ (1)
For school b ⇒ 10m + 10n = 390
⇒ m + n = 39
⇒ m = 39 – n ⇒ (2)
Substitute (2) in (1)
9(39 – n) + 5n = 267
⇒ 351 – 9n + 5n = 267
⇒ 9n – 5n = 351 – 267
⇒ 4n = 84
⇒ n = 21
Then, m + 21 = 39
⇒ m = 39 – 21
⇒ m = 18
Hence, van can carry 18 students and bus can carry 21 students.

approximation for the human population (in billions) of Earth in 2020?
Answer:
9.89 billion
Step-by-step explanation:
At that rate of growth, the population is multiplied by 1.023 each year. After 22 years, the population would be ...
6·1.023^22 ≈ 9.89 . . . billion
Answer:
Let the equation for the population (P) growth be given by
P = P0ert, where P0 is the initial population in billioins at time t,
t is the number of years since 1987,
r is the rate of growth of population/year
In this case P0 = 5 billion and r = 0.02. Putting these values into the equaation:
P = 5e0.02t
Year 1995 is 8 years after 1987, then the population would be
P = 5e0.02*8 = 5e0.16 ≈ 5.87 billion people

Answer:
(-4,-5)
y= -5
x= -4
Step-by-step explanation:
y=3/2x+1
y=3/4x-2
solve using the comparison method
3/2x+1=3/4x-2
subtract 3/2 from both sides
-3/4x+1=-2
subtract 1 from both sides
3/4x=-3
divide both sides by 3/4
x= -4
substitute the value of x into an equation
y=3/2(-4)+1
distribute
y= -6+1
add, but 6 is negative so subtract
y= -5
