Answer:
10/27
Step-by-step explanation:
To figure this out, first subtract 8/15 from 6/5.
Before we can do that though, we need a common denominator. The LCM of 5 and 15 is 15. (5 * 3 = 15; 15 * 1 = 15) 8/15 already has 15 has a denominator, so that doesn't need to be modified. 6/5 becomes 18/15 (6 * 3 = 18).
Subtract 8/15 from 18/15 to get 10/15. This simplifies to 2/3.
Now, multiply 2/3 by 5/9 (reciprocal of 9/5). That equals 10/27. There is no need to reduce, as it is already simplified.
Use substitution to find the ordered pair of the following system of equations:
y=6x
y=5x+7
(_,_)
Answer:
first substitute 'y' in 2nd equation by right side of 1st one and you get:
now substract 5x from both sides of 2nd equal and you get:
as a result of the equal above you get:
now substitute x in very first equation by the result from above (x=7):

Question Help;
Sheldon can read 8 pages in 15 minutes. Amy can read 16 pages in 1 hour. Explain how you could use a table or graph to find how much longer it would take Amy to read a 320-page book than Sheldon.
Answer:
First you must convert time to the same units.
8pages/15min= 32pages/1 hr
now you can clearly see the ratio
Amy: 16/hr
Sheldon: 32/hr
We can see that Sheldon reads twice as fast as Amy.
This should be a good starting point, sorry I don't have much time to finish this question. Hope this helps good luck!
