Answer:
Step-by-step explanation:
1/4x-2 because you subtract the x from both sides, then you add 8 to both sides. Next you divide both sides by -4 to get y=1/4x-2
Create 2 eq’n, let V = vans and B= buses
1. 150 = 8v + 14b
2. b + v = 15
isolate one variable and substitute it in to an equation:
b = 15 - v
sub “b” into first equation above:
150 = 8v + 14 ( 15 - v)
150 = 8v + 210 - 14v
-60 = -6v
10 = v
sub “v” into equation 2
b = 15 - v
b = 15 - (10)
b= 5
there will be 5 buses and 10 vans to hold 150 students.
Answer:
