Answer:
x = 18 and y = 11
Step-by-step explanation:
The angles 6x - 16 and 92 are vertical angles and congruent, thus
6x - 16 = 92 ( add 16 to both sides )
6x = 108 ( divide both sides by 6 )
x = 18
Angles 8y and 92 form a straight angle and are supplementary, thus
8y + 92 = 180 ( subtract 92 from both sides )
8y = 88 ( divide both sides by 8 )
y = 11

Answer:
4 hours 55 minutes
Step-by-step explanation:
Time, speed, and distance are related by ...
t = d/s
t = (177 mi)/(36 mi/h) = 4 33/36 h = 4 11/12 h
The fractional part of this time is ...
11/12 hour is (11/12)(60) = 55 minutes
The van will take 4 hours and 55 minutes to travel a distance of 177 miles.
Answer:
72.
Step-by-step explanation:
Number of strings with exactly 2 1's
= 9C2
= 9*8/2*1
= 36.
Same for 2 0s
= 36.
-2x + 6 - 13x + 16
= -15x + 22
Sin(A) = opposite/hypotenuse = 12/13
Cos(A) = adjacent/hypotenuse = 5/13
Tan(A) = opposite/adjacent = 12/5
