What was the number of children and the number of adults who took the train ride that day, and which pair of equations can be solved to find the numbers?

Respuesta :

a + c = 27 and 4a + c = 60
3a = 60 - 27 = 33
a= 11 
so c = 16
11 adults and 16 children

The number of children that took the train ride is 16.

The number of adults that took the train ride is 11.

The pair of equations that can be used to find the numbers are: 4a + c = 60  and a + c = 27

What are the linear equations that represent this question?

4a + c = 60 equation 1

a + c = 27 equation 2

How many adults took the train ride?

In order to determine this value, subtract equation 2 from equation 1

3a = 33

Divide both sides by 3

a = 33/3

a = 11

How many children took the train ride?

Substitute for a in equation 2

11 + c = 27

c = 27 - 11

c = 16
