48/3=16 16 is 1/3 of the kids on the trip, therefore 2/3 is 32 plus 8 is 40
40 people
Answer:
D = 240 - 30t
Step-by-step explanation:
If the equation represents her distance from City A, we need to include 240 in the equation to represent the distance to the city.
Then, we need to subtract 30t from 240 in the equation because 30t represents how far she will have traveled in t hours.
So, D = 240 - 30t is the equation that will represent Layla's distance from the city.

Using x as the number of adult tickets sold
If 3x as many student tickets were sold as adults
--> the number of student tickets is 3x
If the total tickets is 572 and made up of 3x and x
This equation represents the relation ship
Total = 572
number of adult tickets + number of student tickets = 572
x + 3x = 572
When solving for x, we will find the number of adult tickets
x+3x =572
4x=572
x= 572/4
x= 143
143 adult tickets were sold

Answer:
x - y = -1 ....... 1
3x + 2y = 22 ........ 2
Make x the subject in the first equation
x = -1+y
Substitute this into the second equation
3(-1+y) + 2y = 22
-3 + 3y + 2y = 22
5y = 25
Divide both sides by 5
y = 5
Substitute y = 5 into x = -1+y
x = -1+5
x = 4
x = 4 , y = 5
Hope this helps
