Not sure what shape it is I’m assuming triangle. With what you have the answer should be 10.7mi
I’m guessing this is combining like terms? -3.1d+2.8h-13
s = # of songs
y = total amount of money
$11 + $1(35) = y
Simplify the right side
$11 + $35 = y
Combine like terms
$46 = y
If he downloaded 35 songs, he would have ti pay $46
If he downloaded s amount of songs, he would have to pay $11 + $1s = y
