Answer:

Step-by-step explanation: first write it as an equation f(x)=15(x) +45 and then plug in 3 because you are finding for 3 hours. It would look like this f(3)=15(3) + 45. Then you solve it, 15 times 3 equals 45. f(3) =45+45 and then add f(3)=45+45. And the answer is f(3)=90. HOPE THAT HELPS.

Jonathan uploaded some original songs and also some pictures. alissa uploaded four times as many songs, but only uploaded twice
lesya [120]

X is the number of songs and Y the number of pics

our 2 equations will be - X+y=11 & 4x+2y=24

consider x=11-y

Lets replace x in 2:

=4(11-y) +2y=24

=44-4y+2y=24

=44-24= 4y-2y

=20= 2y

=Y=20/2

=Y=10

Lets replace y in 1

=X+10=11

=X=11-10

=X=1
