Adump truck can hold 2 1/4 tons of gravel. the pay loader loading the truck puts 750 pounds of gravel in the truck at one time. how many loads does the pay loader need to dump in the truck before it is full? 6 loads 5 1/2 loads 5 loads 4 3/4 loads

6 loads

Step-by-step explanation:

Given: The amount of gravel hold by a dump truck =

The pay loader loading the truck puts 750 pounds of gravel in the truck at one time.

We know that 1 ton = 2,000 pounds

Therefore,

Now, the number of loads needed by the pay loader to dump in the truck before it is full is given by :_

Hence, the pay loader needs 6 loads to dump in the truck before it is full.

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:
