Answer:
585/3 = 195 students
Step-by-step explanation:Each group of three created (or used) 9 pictures, so that means three pictures per student.
Dividing 585 students by 3 pictures per student means that there are 585/3=195 students.
Answer:
Students(s) = 192.
Step-by-step explanation:
Eq:
3s + 9 = 585 (each group of 3 wrote 9 each, so for every group + 9. S = students and 585 is altogether.)
Isolate the 3s by doing the inverse (-) of addition and we do that by subtracting 9 from itself and 585.
Eq: 3s = 576
Lastly, isolate the s by dividing 3 (inverse of *)
Eq:
576
___
3
( s = 192 )
