Y = 10n + 500....after 20 weeks...n = 20
y = 10(20) + 500
y = 200 + 500
y = 700 <== she will have 700 songs at the end of 20 weeks

Answer:
4
Step-by-step explanation:
The formulae for Curved surface
area = πrh
Area = 88cm2
height = 14cm
radius = ?
Let π be 22/7
88 = 22/7 x r x 14
cross multiply
88 x 7 = 22 x 14 x r
616 = 308r
Divide both sides by 308
r = 2
Diameter = Radius x 2
so our radius is 2, 2 x 2 = 4
Hello there!
To solve this system using substitution, notice that you already have one variable, x, solved for:
x=5-3y
Now, plug 5-3y in place of x in the other equation, -6x+5y=16:
-6(5-3y)+5y=16
Now simplify:
-6(5-3y)+5y=16
-30+18y+5y=16
-30+23y=16
23y=46
y=2
Now that you have y=2, plug this value in place of y into any of the two equations to solve for x:
x=5-3(2)
x=4-6
x=-1
Therefore, your final answers are that x=-1 and y=2 or (-1,2)
