The high school took two field trips to the Newport Aquarium many many years ago. They used school buses and vans to transport all the students. On the first trip there were 3 vans and two buses with 122 students. The second trip was more popular, with 5 vans and 3 buses, carrying 189 students. Use a system of equations to determine the number of students that a van and a bus can carry `

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

-2 is the right
