A diver ascended 8/9 of a meter in 1/9 of a minute. What was the diver's rate of ascent in meters per minute?

8m/mins

Step-by-step explanation:

The following were obtained from the question:

Distance = 8/9m

Time = 1/9min

Rate = Distance /time

Rate = (8/9) / (1/9) = 8/9 x 9

Rate = 8m/mins

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:

can you rephrase the question ? it is unclear : -)
