On her map 1 inch is equal to 20 miles.
5x=100
divide both sides by 5
x=20
5 is for the 5 inches.
x is for the unknown.
100 is the 100 miles between the cities.
So the scale 1:20
Answer:
m2 = - 1
Step-by-step explanation:
Subtract x from both sides of the equation
-y = - x - 3
Divide by - 1
-y/-1 = -x/-1 - 3/-1
y = x + 3
The slope of the line we were given is 1. The 1 is in front of the x
m1 * m2 = - 1
m1 = 1
1*m2 = - 1
m2 = - 1
Answer:
x=1.4
Step-by-step explanation:
7x-1=1.3x-8.9
7x-1.3x= -8.9+1
5.7x= -7.9
x= -79/57
or x=1.38
Answer:
1080 degrees
Step-by-step explanation:
The sum of the interior angles of any polygon is:
Sum = (n - 2) * 180
Where n represents the number of vertices of the polygon
This polygon has 8 vertices so:
(8-2) * 180 = 6*180 = 1080 degrees
