Answer:
-1/4= -0.25
Step-by-step explanation:
6*5=30
6*-8=-48
30-48+12=54
30+12=42
42-48x=54
42-42-48x=54-42
-48x=12
-48x/-48=12/-48= -0.25

Which system of equations can the librarians use to model this situation?
Answer:
system of equations are
Step-by-step explanation:
Let x = number of children's books sold,
and let y = the number of adult books sold

so,
system of equations are
