If the average (arithmetic mean) of the five numbers x, 7, 2, 16, and 11 is equal to the median of the five numbers, what is the value of x ? (1) 7 < x < 11 (2) x is the median of the five numbers. if the average (arithmetic mean) of the five numbers x, 7, 2, 16, and 11 is equal to the median of the five numbers, what is the value of x ? (1) 7 < x < 11 (2) x is the median of the five numbers.

Step-by-step explanation:

Given are five numbers x, 7, 2, 16, and 11

Average = sum/5=

Median =

The average of the remaining four numbers =

If x=9 then average =9 only and also median

will be middle entry of ascending order

2,7,9,11,16

Middle entry = Median = 9

Hence x=9

(1) 7 < x < 11

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:
