Answer:

x= −2 /7 y+ −17 /7

Step-by-step explanation:

well 3y and -y together make 2y. 2x and 5x make 7x. -5 and -12 make -17. then you get 7x+2y=-17.  Let's solve for x.

7x+2y=−17

Step 1: Add -2y to both sides.

7x+2y+−2y=−17+−2y

7x=−2y−17

Step 2: Divide both sides by 7.

7x

7 = −2y−17 /7

x= −2 /7 y+ −17 /7

x= −2 /7 y+ −17 /7

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
