The state fair is a popular field trip destination. This year the senior class at High School A and the senior class at High Sch
nata0808 [166]

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)\\

Multiply 2 to both the sides of equation (2), we get

16x+10y=528.......................(3)

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

15x=270\\\Rightarrow\ x=\frac{270}{15}\\\Rightarrow\ x=18

Substitute value of x in (1), we get

18+10y=258\\\Rightarrow\ 10y=240\\\Rightarrow\ y=24

Hence, there are 18 students in a van and 24 students in a bus.

VladimirAG [237]

Answer: -11

Step-by-step explanation:

For this problem, it is important to look at the domains next to the function. In this problem there is a function for when x < 1 and when x ≥ 1. 3 is greater than 1, so we will use the second equation.

From there, plug in 3 for x and solve.

-2x - 5

-2(3) - 5

-6 - 5

-11
