Answer 1

Please help write an algebraic expression for there are at least four hundred students in the seventh grade

Let N7 be the number of students in 7th grade at any particular time.

Then we cam write,

N7 > 400

This tells us that the number of students in 7th grade is greater than 400.

i.e. there are at least 400 students in 7th grade.
