A. x = 2544 divided by 25
x= 101.76
B. x = 2150 divided by 20
x = 107.5
I hope this helps let me know if you need more.
1000 x 8% = 80
so you would get 80 dollars extra a year times 10 years
80 x 10 = 800
1000 + 800 = $1800
so at the end of the ten years you will have $1800
<span>Krystal's rate = 1 floor in 16 min. = 1/16 floors per min.
Working together their rate = 1 floor in 5.76 min. = 1/5.76 floors per min.
We need to determine Perry's rate, so we need to equate their combined rate with the sum of the individual rates.
Let Perry's time = x
In equation form, we can write:
1/16 + 1/x = 1/5.76
Solve for x:
(x+16)/16x = 1/5.76 -> 5.76(x+16) = 16x -> 10.24x = 92.16 -> x = 9
So, Perry would take 9 mins. to do the floor alone.
I hope this helped!

For this case we have the following system of equations:
We multiply the second equation by -3:
Thus, we observe that the second equation is equivalent to the first, if we add both we get:
The equality is fulfilled. The lines are on top of each other.
Answer:
Infinite solutions
Answer:
c-12
Step-by-step explanation:
If there's -9 c's and plus 9 c's then they cancel each other out and become just c
