You can use the equation d = 4.7 + 2.8t to model a walk in which the distance from a motion sensor d is measured in feet and the time t is measured in seconds.
Use the equation to plug in the values and answer the questions.
c. When will the walker be 15 feet away from the sensor? I’m

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

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:
