Answer:
The food will last for 25 days with 72 boys
Step-by-step explanation:
Proportions can be used to find the number of days the food will last for 72 boys.
60 boys in a hostel have food for 30 days.
Let x be the number of days for which the food will last
The proportion or product of both scenarios has to be same as the number of days and number of boys are proportional
Which means
![60*30 = 72 * x\\x = \frac{60*30}{72}\\x = 25](https://tex.z-dn.net/?f=60%2A30%20%3D%2072%20%2A%20x%5C%5Cx%20%3D%20%5Cfrac%7B60%2A30%7D%7B72%7D%5C%5Cx%20%3D%2025)
Hence,
The food will last for 25 days with 72 boys
Answer:
The answer is (4,-2)
Step-by-step explanation:
y=x-6
3x+2y=8
3x+2(x-6)=8
3x+2x-12=8 Combine like terms
3x+2x-12+12=8+12 add 12 to both sides then combine
5x=20→ x=4
then plug it in to y=x-6→y=4-6→y=-2
