<span>50844, i looked it up on the online calculator</span>
25 Dollars
15x100/60=25$
i got the 60 from 100-40 (40%off)
then 15 times 100 and divide that by 60
For the linear system :
r+t = 20 and 5(r+t) = 150
If you sub in the first equation into the second, you will get: 100 = 150, which is incorrect
It means the system does NOT have solutions.
Answer will be the last choice
Answer:
-7
Step-by-step explanation:
It has been awhile since I worked with in qualities but I got the answer,
-1/3 < or equal to p < or equal to 2.
I multiplied the 5 in the middle of the equation with what's in parentheses to get 15p - 10, then I added 10 to both outer sides of the equation and got
-5 < or equal to 15p < or equal to 30.
Then lastly I divided 15 by -5 and 30!
I hope that's right.. I'm sorry if it isn't!
