Kevin is downloading songs and albums. It costs him $0.50 to download a song and $4.00 to download an album. Kevin has $15.00 to spend. If a represents the amounts of albums he can download and s represents the amount of songs he can download, which equation matches his scenario?

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
