Answer:
20
Step-by-step explanation:
We have two simultaneous equations.
(1) y = 2x + 50
(2) y = 4.5x
1. Subtract (1) from (2)
0 = 2.5x - 50
2. Add 50 to each side
2.5x = 50
3. Divide each side by 2.5
x = 20

Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 5) and (x₂, y₂ ) = (8, 3)
m = 
= 
= -

Answer:
<u>The dimensions of the real store are 80 times bigger as per scale:</u>
- 1.875 in * 80 = 150 in = 150/12 ft = 12.5 ft
- 2.25 in * 80 = 180 in = 180/12 ft = 15 ft
<u>The area of the real store:</u>
- 150 in * 180 in = 27000 in²
- 12.5 ft * 15 ft = 187.5 ft²
