Step-by-step explanation:
Answer: 25 days
Step-by-step explanation:
The original number of students in the hostel was 50, and now it is 80 because 30 joined. So the original number of students was 5/8 of what it is now.
I use the inverse formula the number of days the food will last.
40 * 5/8 = 200/8 = 25
If there are 80 students, then the food will only last for 25 days.
So to find x, you have to add both A and B which is 38. Since AuB (excluding the overlap) is 29, subtract 38 from 29 and you get 9 for x.
Yas! systems of equations
convert one equation so that a single variable is one one side
x = 65 - 2y
plug it in the other equation
2(65 - 2y) + 3y = 105
130 - 4y + 3y = 105
130 - y = 105
25 = y
