X=4 because first u distruste and add the numbers then add 33 to both side
A linear pair means both angles add up to 180
first we want to find x
(x-15)+(x+77)=180
2x+62=180
2x=118
x=59
then just put x into the two angles
59-15
m1=44
59+77
m2=136
It is the second one. just did this like 2 days ago
Answer:
x = -1/13 = -0.077
Step-by-step explanation:
1.1 Solve : 13x+1 = 0
Subtract 1 from both sides of the equation :
13x = -1
Divide both sides of the equation by 13:
x = -1/13 = -0.077
One solution was found :
x = -1/13 = -0.077

Answer:
19/21 hours, about 54 minutes 17 seconds
Step-by-step explanation:
The time is found from ...
time = distance/speed
time = (95 mi)/(105 mi/h) = 95/105 h = 19/21 h
The trains will meet after 19/21 hours, about 54 minutes, 17 seconds.
