Question

the 7th grade class at a school has 11 more students than the 6th grade class. the 8th grade class has 10% fewer students than the 7th grade class. there are 63 students in the 8th grade class. 7th grade: s + 11, 8th grade: 63, 10% fewer students than the 7th grade class = 8th grade class, 0.9(s + 11) = \square

Explanation:

Step1: Understand the equation

The equation given is \(0.9(s + 11)=\square\), and we know from the problem that the 8th grade class has 63 students. So we need to set the left - hand side equal to the number of 8th grade students.

Step2: Substitute the value

Since the number of 8th grade students is 63, we substitute the right - hand side of the equation with 63. So \(0.9(s + 11)=63\).

Answer:

63
