3 = X/2 + 2
1 = X/2
2 = X
Jan had 2 pencils to start off with. She gave half (1 pencil) to Talia. Her brother gave her 2, which means she ends up with 3.
Answer:

Explanation:
From the question, we have it that the probability of heads coming up every time or tail coming up every time is 1:7 if the coin is tossed in 4 tosses
What this means is that we have a probability of 1/8 of head showing up and a probability of 7/8 that a tail will show up in each toss of the coin
For four throws, it means all four are heads or all four are tails
If all four are heads, we have the probability of this happening as:

if all four are tails, we have the probability as:

Now, the probability of either heads or all tails after 4 tosses will be:
All we need to do is multiply.
6 miles * 28 days = 168 total miles ran in 28 days.
Therefore, the answer is 168 miles
Best of Luck!
I'm really sorry if I'm wrong but
14*26=364 so he can go 364 miles for every full tank so his first 364 are covered since he starts with a full tank.
Step 2:
838/26*14 = <span>451
</span>
step 3:
He'd only have to stop once
The angles of a triangle always add up to 180°.
By simply adding the angles and checking the total, you can tell if they make a triangle or not.
Using this property, 5 won't make a triangle, 6 will.
Hope this helps! :D
