Ben finds 4 + 11 using a number line. He counts 11 on from 4. Which is a faster way to solve this problem

Step-by-step explanation:

The way to solve the problem would be just add the two number as 11+4 =15.

This would avoid the tedious process first drawing the number line and then counting each number to reach the same answer, which could be easily reached by just adding the two numbers.

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:
