The number of runs scored by the home team at a base ball game is represented by (x + 7). The number of runs scored by the visiting team is represented by (3x - 7).

Given :

Runs scored by home team is (x + 7).

Runs scored by visiting team is (3x - 7).

To Find :

An expression to find how many more runs the home team scored than the visiting team. Then evaluate the expression if the value of x is 6.

Solution :

Let, number of more runs the home team scored than the visiting team is R.

R = (x + 7) - (3x - 7)

R = 14 - 2x

Now, putting value of x = 6 in above equation, we get :

R = 14 - 2( 6 )

R = 2

Hence, this is the required solution.

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:
