On a bike trip across the united states rodney notes that he covers about 190 miles every 4 days. if he continues at this rate, use a ratio table to determine about how many miles he could bike, in 6 days.

Rodney travels a distance of 190 miles in 4 days. 
The question wants to find the distance Rodney can travel in 6 days using a ratio table.

The distances travelled per day would be:

Distance travelled in 1 day = (190/4) miles = 47.5 miles
Distance travelled on the 2nd day = (47.5 * 2) miles = 95 miles
Distance travelled on the 3rd day = ( 47.5 * 3) miles = 142.5 miles
Distance travelled on the 4th day is given and it is 190 miles.
Distance travelled on the 5th day = ( 47.5 * 5) miles = 237.5 miles
Distance travelled on the 6th day = (47.5 * 6) miles = 285 miles

So this can be put in a ratio table and the distance travelled by Rodney on the 6th day is 285 miles.

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:
