Well, since it is $1.35 to download each song, you can use the equation y=1.35x to solve the cost of 25 songs. y=1.35(25)=33.75 so the cost of 25 songs is $33.75. Hope this helps! -Raiden
The equation is y = x X 1.35 The x represent how many digital song, and the y represent the total cost. You need to do 25 times 1.35 which equal 33.75. So the answer is $33.75
You use Pythagoras theorem for this: You add 52 and 20 for AC which is 72 So you do X^2 = 72^2 + 30^2 X^2 =5184 + 900 X^2= 6084 X = 6084 squared root X= 78
