If you multiply the numerator and the denominator of 1/3 by 4, you will get a common denominator.
1/3 = 4/12
Then you can add:
6/12 +4/12 = 10/12
Just add the top 2 numbers and the bottom 2 stay the same. Then you can simplify. 2 goes into both 10 and 12, so divide them both by 2 and you get 5/6 as your answer.
Answer:
2
Step-by-step explanation:
Using the distance formula,

We just need to plug in the numbers.
So 
Then we simplify it to

Finally, we get
, which is
when simplified.
The answer is A: 1/2 because if you divide the length of AB by 2, you will get the corresponding line EF.
Answer:
Step-by-step explanation:
arithmetic sequence: 60,68,76,......
a = 60
d = 68 - 60 = 8
an = a + (n-1)*d
a20 = 60 + 19 * 8
= 60 + 152
= 112
There are 112 seats in the 20th row
