1\2-1\8= get the lcm of 2 8=8
(8\2+1=5)(8\8+1=1)
5\8-1\8=4\8=1\2
To find your answer you'd first add up all of their laps that they had completed over the 3 weekends.
8,597 + 11,065 + 9,211 =28,873 laps.
Afterwards, you'd subtract 28,873 from the original 40,000 goal and end up with 11,127 more laps as your answer.
Hi there,
Remove parenthesis,
7 + 9 + (-4)
Then, use the addition and subtraction rules:
7 + 9 - 4
Hence, the answer is 12 (C)
Hope this helps :)
Answer:
the second one
Step-by-step explanation:
Looking at Pascal's Triangle, specifically at the row that starts with 1, 10, etc we see the value 210 in the 4th slot (start the count at 0) since 10-6 = 4
Or you can use the combination formula nCr to get the same result
nCr = (n!)/(r!*(n-r)!)
10C4 = (10!)/(4!(10-4)!)
<span>10C4 = (10!)/(4!*6!)
</span><span>10C4 = (10*9*8*7*6!)/(4!*6!)
</span><span>10C4 = (10*9*8*7)/(4!)
</span><span>10C4 = (10*9*8*7)/(4*3*2*1)
</span>10C4 = 210
Either way, the final answer is Choice C) 210
