Answer:

Step-by-step explanation:

\frac{2}{k^2-2k}=1-\frac{1}{k^2-2k}

multiply by \frac{k^2-2k}{1} on each side

2=k^2-2k-1

add 1 on both sides 3=k^2-2k

make it equal 0

0=k^2-2k-3

Factor

(k-3)(k+1)

answer is 3 and -1

Brandon earns a rebate each month on his meals and movie tickets. He earns $0.50 for each movie ticket and $2 for each meal. Las
AURORKA [14]

Let ticket be x and meal be y

So $0.50 for each movie ticket = 0.50x

$2 for each meal = 2y


He purchased 22 tickets, so x = 22

0.50 * 22 = $ 11


Now the total value is $25 (with both ticket and meal)

total = t

0.50x + 2y = t

you know x = 22 and t = 25

11 + 2y = 25


Part A)

2y = 25 -11

y = 14/2

y = 7

Number of meal is 7


Part B)

(don't know about part B)

0.50x + 2y = 25

0.50(22) + 2(7) = 25

11 + 14 = 25

25 = 25

188 to 42 what is the percent change
Mekhanik [1.2K]

Answer:

Step-by-step explanation:

so we are gonna have a percent decrease because it went from 188 to 42

decrease = (original number - new number) / (original number ) * 100

                = (188 - 42) / (188) * 100

                = (146 / 188) * 100

                = 0.7766 * 100

                = 77.66% decrease....not sure if u need ur answer rounded to the nearest percent or not....if so, its a 78% decrease
