500 songs in his music player: + 500
every week he adds 10 songs: 10n (n is how many weeks)
equation: s = 10n + 500 (s is the total amount of songs)
after 20 weeks? : plug it in
s = (10 x 20) + 500
s = 200 + 500
s = 700
he will have 700 songs in his music player after 20 weeks
Answer x=5, y= 3.5
Find y by plugging the x value into the 2nd equation
4(2y-2) -9=11
8y - 8 - 9 =11 combine like terms
8y = 28 divide both sides by 8
y = 3.5
Now find x
Plug your y value into first equation
X = 2(3.5) -2
X= 7-2
X=5
You can check your work by putting your x or y values into the equations
For the first equation
5=2(3.5) -2
5=5
For the second equation
4(5) -9 = 11
20 - 9 = 11
11 =11
The information given in the triangle shows that the total distance from A to B to C to D to E will be C. 84.
<h3>How to calculate the triangle?</h3>
From the information given, ABF = EDG, GCF are equilateral and AG = 21 while CG = 1/4.
The total distance from A to B to C to D to E will be:
= 21/CG
= 21 / 1/4
= 21/0.25
= 84
In conclusion, the correct option is 84.

Answer:
169 sq. units
Step-by-step explanation:
If the perimeter of a square is 52, then one of its side lengths will be 13. This is because the side lengths of a square are all equal: you can find the length of one side by just dividing the perimeter by 4. Now that you have the length of one side, you can find the area of a square by multiplying said length by itself. 13 x 13 = 169.
