Explain how the architect created a scale drawing of the house. What scale did she use?

Scale used for drawing is 1 cm = 1.75 m

Step-by-step explanation:

An architect makes a scale drawing of a house.

Actual width of porch  = 7 meters

Width of porch on drawing = 4 cm

So, Actual width = Drawing width

So, 4 cm = 7 m

1 cm = 1.75 m

So, Scale: 1 cm = 1.75 m

So, Option B is correct

B)1 cm = 1.75 m

Hence scale used for drawing is 1 cm = 1.75 m

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:
