Expression simplified: ![x+9y+7](https://tex.z-dn.net/?f=x%2B9y%2B7)
Step-by-step explanation:
The expression that we have in this problem is:
![x+y\cdot 9 +3 +4](https://tex.z-dn.net/?f=x%2By%5Ccdot%209%20%2B3%20%2B4)
The first type of operation that we have to solve in such expression are multiplication/division.
In this expression, there is only one multiplication, that is:
![y\cdot 9 = 9y](https://tex.z-dn.net/?f=y%5Ccdot%209%20%3D%209y)
So we can rewrite the expression as
![x+9y+3+4](https://tex.z-dn.net/?f=x%2B9y%2B3%2B4)
Now we can evaluate the sum of the similar terms: in this case, similar terms are only 3 and 4, and their sum is
![3+4=7](https://tex.z-dn.net/?f=3%2B4%3D7)
Therefore, the expression can be rewritten as
![x+9y+7](https://tex.z-dn.net/?f=x%2B9y%2B7)

We are given
The largest telescope in the world is powerful enough to identify a penny that is 5 miles away
it means that
distance =5 miles
we can change it into yards
we know that
1 mile=1760 yards
![d=5\times 1mile](https://tex.z-dn.net/?f=d%3D5%5Ctimes%201mile)
we can replace 1 mile
![d=5\times 1760 yards](https://tex.z-dn.net/?f=d%3D5%5Ctimes%201760%20yards)
![d=8800 yards](https://tex.z-dn.net/?f=d%3D8800%20yards)
So, distance in yards is 8800 yards..........Answer
