Ms. Lovell has n students in her class. Today 4 new students joined her class. Which expression describes the number of students in the class today?

Hi im adrian and im in 4th grade. the answer is n+4

Step-by-step explanation:

You start with n then 4 new students join, so thats n+4

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
