High School

A school has 764 students. Of the students, 118 are in third grade. Which equation can be used to find \( s \), the total number of students in all of the other grades?

A. \( 764 + 118 = s \)
B. \( s = 764 - 118 \)
C. \( 118 = 764 \)
D. \( 118 + s = 764 \)

Answer :

I think it’s the first one because it says S represents the total so I’m guessing to add 764 and 118 and it will get you the total.

Answer:

D. 118 + s = 764

Step-by-step explanation:

To find the total number of students in all the other grades, if we only know the total number of students in the school and the number of kids in 3rd grade, we need to subtract the kids in 3rd grade from the entire school. This leaves us with 646.

s = 646
