Step-by-step explanation:
x = angle 1
3x + 12 = angle 2
angle 1 + angle 2 = 180
4x + 12 = 180
4x = 168
x = 42 = angle 1
180 - 42 = 138 = angle 2

Answer: 160 miles
Step-by-step explanation:
Given that :
Miles ran = r ; at the speed of 5 miles per hour
Miles biked = b ; at the speed of 10 miles per hour
Total miles biked and ran = 200 miles
If she biked for twice as many hours as she ran
Let hours
Total number of miles Morgan biked
r + b = 200 - - - (1)
From speed = distance / time
Hours biked = distance / speed = b / 10
Hours ran = distance /speed = r / 5
b/ 10 = 2 (r/5)
b / 10 = 2r / 5
Cross multiply
5b = 20r
b = 4r
Substitute into (1)
r + b = 200
r + 4r = 200
5r = 200
r = 200/5
r = 40 miles
Total number of Miles biked ;
r + b = 200
40 + b = 200
b = 200 - 40
b = 160 miles
You divide both sides by 0 so y=0
We see that the -2 is smaller than 3, so we will write this statement using this inequality:
-2 < c < -3
