First, you do the distributive property on:
4(2n+3)
You would get
8n+12
Then add the original part of the equation in (4n)
4n+8n+12
Combine like terms
12n+12 is the answer
3/4 divided by 4 is 0.1875
I'm not really sure If I would be much help but I'll try best k? (cries a little) So you do 100
+ 6.0
+ 4.0

11 .0
So your answer is 11.0 for the tall tree.
Myles ran 2 times what alison ran:
2x21 = 42
Hector ran 5 times as many miles as Myles:
42x5 = 210
therefore Hector ran 210 miles.
