I really need help, Physics isn't my strong subject at all! Question: Runner A starts at x = 0 and runs with a velocity of + 3.0 m/s toward runner B. Runner B starts at the same time at x = 20 m and runs with a velocity of -2.0 m/s toward runner A. Where do they meet, and how much time has elapsed since they started running?

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

unless if u could do my questions, if not i wouldn't want to

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
