Let 
be the amount of food needed for one man for one day. At the beginning, we have enough food for 400 men for 40 days, i.e.
After 10 days, the 400 men will have consumed
food, impliying that the food remaining is
If 200 more men join the garrison, there are now 600 men. Each of them requires food each day, and there are 
units of food remaining. They will last
days.
-mn^2-5m^2/(5m-2)(m+4n)

Answer:
X=4,4
Step-by-step explanation:
2 x^2 – 16 x + 32 = 0
2(x^2-8x+16)=0
X^2-(4+4)X+16=0
x^2-4x-4x+16=0
x(x-4)-4(x-4)=0
(x-4)(x-4)=0
X=4,4
So the solution is X=4,4
Answer:
The total amount of money pays by Adrian is $14.5 .
Step-by-step explanation:
As given
Adrian purchases six tubes of paint and three paint brushes at a craft store.
Each tube of paint cost $2.50 each paint brush cost $0.50 .
Total cost of the 6 tubes of paints and 3 paint brushes = 6 × Cost of each tube of paint + 3 × Cost of each paint brush cost .
Putting the values in the above
Total cost of the 6 tubes of paints and 3 paint brushes = 6 × 2.50 + 0.50 × 3
= 15 + 1.5
= $16.5
As given
Adrian has a coupon for $2 of his purchase .
Total amount money pay by Adrian = Total cost of the 6 tubes of paints and 3 paint brushes - Coupon cost
Putting the values in the above
= $16.5 - $2
= $ 14.5
Therefore the total amount of money pays by Adrian is $14.5 .
