Answer:
(4a^5b^6)^4 = 256a^20b^24
Step-by-step explanation:
Alright, this is simple. You know what the new number is, 54. You know the original number was decreased by 40%. Your looking for the original number, X. So set up an equation.
x-.4x=54
When X stands by itself, it's perceived to value 1.00
1.00-.4x=54
(1.00-.4 [40%]=.6)
.6x=54
Divide both sides by .6 to eliminate everything else.
.6x/.6=54/.6
You get 90. Your original number was indeed 90.
To check it, we can do 90/40%, or 90/.4=54
~Hope this helps!

Step-by-step explanation:
U should use the system of 2 equations.
Let x be the rental cost of a movie and let y be that of video games.
{12x + 2y= 41} eq1
{3x + 5y= 35}eq2 note: eq means equation
The answer is
X=2.5 Y=5.5
So, the rental cost for each movie is 2.5$
and for each video game is 5.5$
