Well, I have an example that might help:
Rico's MP3 player holds songs of three different genres: grindcore, zydeco, and kuduro. There are <span>55</span> times as many grindcore tracks as there are zydeco tracks, and there are <span>77</span> times as many kuduro tracks as there are zydeco tracks. Let <span>xx</span> represent the number of zydeco tracks. Write an expression for the total number of tracks on the MP3 player, and simplify it.
Multiply the number of zydeco tracks by <span>55</span> to get the number of grindcore tracks.
<span><span>5x</span><span>5x</span></span>
Multiply the number of zydeco tracks by <span>77</span> to get the number of kuduro tracks.
<span><span>7x</span><span>7x</span></span>
Add up the numbers of all the tracks.
<span><span>x+5x+7x</span><span>x+5x+7x</span></span>
Simplify using the distributive property.
<span><span><span>=(1+5+7)x</span><span>=13x</span></span><span><span>=(1+5+7)x</span><span>=13x</span></span></span>
So, Rico's MP3 player holds <span><span>13x</span><span>13x</span></span> tracks.

Answer:
2.2% per year
Step-by-step explanation:
<u>Problem:</u>
You deposit $500 into a bank account and received $55 simple interest after 5 years. What had been the interest rate?
<u>Result:</u>
The interest rate was 2.2% per year.
Explanation:
Find interest rate by using the formula I = P*i*t , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years. In this example I = $55, P = $500 and t = 5 years, so
i = 55/500*5
i=0.022 = 2.2% per year
Hope it helps XD
