Question 57363: The American Kennel Club recognizes 7 categories of dogs plus one for miscellaneous breeds. In 2002 Dual Championships were awarded to 141 dogs. Dual champions are dogs that show excellence in both breed standard and ability to perform the function for that breed. Out of those 141 dogs, one was awarded to a dog in the toy class and 3 to dogs in the herding breeds. The remaining Dual Championships were awarded to dogs in the sporting breeds and the hound breeds. There were 93 more Dual Championships awarded to dogs in the hound breeds than the sporting breeds. (Source: American Kennel Club)
Let s = number of sporting breeds awarded Dual Championships
Let h = number of hound breeds awarded Dual Championships.

Let s = number of sporting breeds awarded Dual Championships
Let h = number of hound breeds awarded Dual Championships.
s+h=1411-1-3=137
h=s+93
or
s+h=137
s-h=-93
.
2. Solve each equation for your variables and express the solution as an ordered pair.
s+h=1411-1-3=137
h=s+93
or
s+h=137
s-h=-93

Question 58037: Need help solving a practice problem, I cannot get this one right!
(5x+3) / (3x)= (7 / 3) - (9 / x)
I tried multiplying (7 / 3)(x / x) and (9 / x)(3 / 3) to get the right side to become:
(7x-27) / (3x) but then I thought I could just get rid of the denominators since they were the same and I'd be left with (5x+3) = (7x-27), which eventually gives an answer of 15. However, when I check the solution of 15 in the original problem it doesn't work out. What am I doing wrong?
Thanks!
Karen

Question 58359: The perimeter of a trapezoid is 94cm. The sides are 6f, 8g-9, 4f, and 7g, where g is twice f. Find the lengths of each side. I decided to try and solve for g first.
8g-9=94-6f-4f-7g
8g-9=94-10f-7g
8g=94+9-10f-7g
8g=103-10f-7g
8g+7g=103-10f
15g=103-10f
g=103-10f/15
I just got lost. Am I am even close?
