Answer:
No Solution
Explanation:
Given the equation:

Step 1: Distribute the terms in the left-hand side.

Step 2: Collect like terms.

Therefore, the equation has No Solution.
If it's just the 7 that's repeating, let
<em>x</em> = 0.1777...
Then
10<em>x</em> = 1.777...
100<em>x</em> = 17.777...
100<em>x</em> - 10<em>x</em> = 17.777... - 1.777...
90<em>x</em> = 16
<em>x</em> = 16/90 = 8/45
If both 1 and 7 are repeating, let
<em>x</em> = 0.171717...
Then
100<em>x</em> = 17.171717...
100<em>x</em> - <em>x</em> = 17.171717... - 0.171717...
99<em>x</em> = 17
<em>x</em> = 17/99
Together they paint 60 feet in an hour. 30 in half an hour.
60 + 60 + 30 = 150.
So it takes two and a half hour.
