Answer:
17.5 page in 25 minutes
Step-by-step explanation:
We can use ratios to solve
7 pages x pages
------------- = ----------------
10 minutes 25 minutes
7 * 25 = 10 x
175 = 10x
Divide by 10
175/10 = 10x/10
17.5 =x

Answer:
18
Step-by-step explanation:
Hello,
In order to solve for x, we need to isolate the variable on one side of the equation.
To do this, we subtract 450 from both sides of the equation, and this will give you:
28.75x = 517.5
As mentioned, we need to isolate x, so we divide both sides by 28.75. This will give the following.
x = 18
Hope this helps!
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.
