Answer:
24 inches represents 9 miles in the map
Step-by-step explanation:
To solve this problem you take into account that 8 inches represents 3 miles and that x represent the number of inches for 9 miles. That is:
8 ------- 3
x ------- 9
This is simply a rule of three, then you calculate:
Hence, 24 inches represents 9 miles in the map
let x = the price of a book
so you would have
total = 3x-20
.2+3.6=3.8 because all you do is add the .2 feet with 3.6 feet
1) 5×4=20mm
2)3×2=6mm
The area=20-6
=14mm
