<span>Let x denote number of ounces of 30-cent iodine.
Mixing of 50 ounces of 18-cent iodine and x ounces of 30-cent iodine will result in (50+x) mixture of iodine. We want the mixture to be worth 20 cent per ounce.
The value of 50 ounces of 18-cent iodine is of course
50â‹…18=900.
Similarly, x ounces of 30-cent iodine is worth 30â‹…x.
Finally, 50+x ounces of 20-cent iodine will cost (50+x)â‹…20.
30x+50â‹…18=(50+x)â‹…20
30x+900=1000+20x
10x=100
x=10</span>

Answer:
a = 24 inches
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 10^2 = 26^2
a^2 + 100 = 676 ////// -100 both sides
a^2 = 576
a = 24 /////UNITS!
a = 24 in.
