2x+6 = 20
take 6 from both sides
2x = 14
divide by 2 on both sides
x = 7
The answer is 6 5/6.
Do you understand why?
If not...be sure to leave comment telling me what u r having problem with.
Glad to help!
Answer:
Formula is 132 - 8n, and there are 52 windows on 10th floor.

the first fllor has 124 windows
Formula:

= 132 - 8n
10th Floor:

First lets figure out 2 and 1/4 as a decimal
2 and 1/4 = 2.25
So now we subtract
5 - 2.25 = 2.75
She is 2.75 miles away from her starting point

Answer:
21.74 ft
Step-by-step explanation:
We use Cosine because we are dealing with the Adj and Hyp
Cos 85 = x/20
x = 20 Cos 85
x = 1.74 feet away from the base of the wall.
Since the ladder is 20 foot long, the total distance will be 1.74 + 20 = 21.74 ft
