You can first set up a ratio to see how many TOTAL computers are needed for a r to 12 ratio.
(5/12) = (x/924) Now cross multiply to solve. 12x = 5(924) 12x = 4620
Divide both sides by 12. x = 385
There are a total of 385 computers needed for the school to have a 5:12 ratio.
Since the school already has 125 computers subtract 385-125 = 260. They need to purchase 260 more computers.
D. no solution
Because they never found each other, the point they cross on is the solution.
I am pretty sure it's 44 degrees.
