Answer: I am not sure how to answer this question besides the fact a inch ruler will have 12 inches. 12 inches equal 1 foot. Each foot is broken down into inches. Hope this helps :)
Step-by-step explanation:
The hardware store sells copper pipes for $24 per 5 feet right? so, 5 feet is equal to 60 inches and since you need 6 inches, you divide 60 by 10 to get 6 and also divide 24 by ten and you get 2.4, so the answer is $2.4 for 6 inches of pipe.
Hope this helps!

5 - 4 + 7x + 1 = 7x + (5 - 4 + 1) = 7x + 2
NO SOLUTIONS:
<em>5 - 4 + 7x + 1 = 7x + a </em><em>(a - any real number, except 2)</em>
ONE SOLUTION:
<em>5 - 4 + 7x + 1 = bx + c </em><em>(b - any real number, except 7, c - any real number)</em>
INFINITELY MANY SOLUTIONS:
<em>5 - 4 + 7x + 1 = 7x + 2</em>
Examples:
2x + 3 = 2x + 5 <em>subtract 2x from both sides</em>
3 = 5 FALSE <em>(NO SOLUTIONS)</em>
2x + 3 = x - 4 <em>subtract x from both sides</em>
x + 3 = -4 <em>subtract 3 from both sides</em>
x = -7 (<em>ONE SOLUTION)</em>
2x + 3 = 2x + 3 <em>subtract 2x from both sides</em>
3 = 3 TRUE <em>(INFINITELY MANY SOLUTIONS)</em>
