Answer:
63*
Step-by-step explanation:
The first thing you need to do is find the value of x. What I did for this was trial and error. I tried a number, and if it was too big, I tried a smaller one. If you add up all of the angles, it should equal up to 180*, so I kept on doing this until I added up to 180.
The answer I got was x=8, so I plugged this into the equation for A and solved. 9x8 is 72, and 72-9 is 63.
Therefore, 63 is the correct answer.
I got 28.93095228, I hope this is the answer
Intersection (repeated element in the set)
A={-9,0,5}
B={0,2,5,8}
C={-9,2,5}
Ans: C, {5}
*In set B and C, element 2 was repeated but not for set A.
Answer:
2.75 hours
Step-by-step explanation:
Speed is 24km per hour (
), and the bus covered 66km.
We need to get a value of <em>km</em> with the rate (24/1) and distance (66) given.
We get: 
.
The km cancel out, leaving us with 66/24 hours, or 2.75 hours.
