On Monday, 169 students went on a field trip to the zoo. All 4 buses were filled and 9 students had to travel in cars. How many students were in each bus

Respuesta :

x(the number of students on the bus)
so
4x=169-9
you get that equation since the number of total students minus the number of students who had to ride in a car now solve
4x=160
you get this by subtracting nine
now divide by four
x=40
