The 2 angles form a linear pair and angles that form a linear pair have a sum of 180 so
10x + 15 + 5x = 180
15 + 15x = 180
180 - 15 = 15x
165 = 15x
11 = x
Answer:
The correct answer would be 4. Explanation below
Step-by-step explanation:
-6x-11x = 68
-6x-11x = -17x
-17x = 68
68/-17 = 4
Hope this helps!

A bicyclist travels at a constant speed of 12 miles per hour for a total of 45 minutes
Domain x is number of hours
Range y is distance traveled
speed = 12 miles per hour
time = 45 minutes = 
= 0.75 hours
We know distance formula
Distance = speed * time
Distance = 12 * 0.75= 9 miles
Number of hours x is 0 to 0.75 hours
So domain is { 
}
Distance is 0 to 9 miles
So range is { 
}
When r is closest to 1, it is a strong positive correlation. When r is closest to -1 it is a strong negative correlation. When r is about 0.8 or anything similar, it is a weak positive. Similar to if r is -0.8 it would be a weak negative correlation. Hope this helps.
Answer:
<em>Diameter= 11.27 feet</em>
Step-by-step explanation:
<em>Circle = 2πr</em>
<em>or, 11.27π = 2πr</em>
<em>or, 11.27π/2π = r</em>
<em>r = 5.635 ft</em>
<em>diameter = 2r</em>
<em>= 2 x 5.635</em>
<em>= 11.27 feet</em>
