Answer:
X/y = 2/5
Y= x+12
Where y = students
X= adults
Number of adults= 8
Number of students= 20
Step-by-step explanation:
The ratio of adults to students on a class field trip is 2 to 5. If there are 12 more students than adults.
Let adult be x
Let student be y
X/y = 2/5
5x= 2y.... equation one
Y= x+12..... equation two
Substituting equation two into equation one
5x= 2(x+12).
5x = 2x +24
3x= 24.
X= 8
Y= x+12
Y= 8+12
Y= 20
Number of adults= 8
Number of students= 20
