Mr. Mandel gave his class 12 minutes to read. 5 1/2 pages in that time. At what rate, in pages per hour, did Claire read?
Eva8 [605]
5 1/2 pages in 12 minutes.
11/2 pages in 12 minutes 

How many pages in an hour?
well, an hour has 60 minutes

Let's write a proportion
11/2 / 12 = x/60
cross multiply
(11/2 * 60) = 12x
330 = 12x
divide both sides by 12
27.5 or 27 1/2 = x

27.5 pages per hour.

Hope this helps

Please help me with this system of equations problem
LekaFEV [45]

Answer:

5x-2y=3

-3x+4y=1

5x-2y=-3x+4y+2

+2y

5x=-3x+6y+2

+3x

8x=6y+2

divide by 2

4x=3y+1

-3y+4x=1

wait so that means that -3x+4y=-3y+4x so that means that both x and y are equal so lets just say their the same

-3x+4x=1

x=1

y=1

Hope This Helps!!!
