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

Answer: 0.475 cups of broth per serving.Explanation:1) Ratio given: i) To facilitate the operations, transform the mixed number 4 3/4 cups into improper fraction:
4 + 3/4 = [16 + 3] / 4 = 19 / 4
ii) ratio broth: servings
2) Proportion with the unknown number of cups of broth per serving:
3) Solve for the unknown:x = [19 / 4] cups × 1 serving / 10 servings = 19 / 40 cups = 0.475 cups

Answer:
The angle is 35
Step-by-step explanation:
The angles are vertical angles, so they are equal
3x-4 = 2x+9
Subtract 2x from each side
3x-2x-4 = 2x+9-2x
x-4 = 9
Add 4 to each side
x-4+4 = 9+4
x=13
But it asked for the measure of the angle
2x+9
2(13)+9
26+9
35
