The scale is 
That means

so
An area of 
on a map represent an area of 
in the city
Applying proportion
Answer:y=4x -7
Step-by-step explanation:
The slope intercept form is: y= mx + b
Y+3 = 4(x-1) step one distribute 4
Y+3= 4x - 4 step two subtract 3 from both sides
Y=4x -7
Answer:
Step-by-step explanation:
4x + 6 + 3x + 21 = 8x + 7
7x + 27 = 8x + 7
-x + 27 = 7
-x = -20
x = 20
m<3= 8(20) + 7
160 + 7 = 167
m<1= 4(20) + 6 = 80 + 6 = 86
m<2= 3(20) + 21 = 60 + 21 = 81
To write 0.1 as a percentage you have to multiply it by 100 and then put the % sign at the end of it.
0.1 X 100 = 10%
It’s important because you may doing something that includes that and you don’t have a ruler etc..
