A music app charges $2 to download the app plus $1.29 per song downloaded. Write a linear equation to find the total cost to download 30 songs.

• y=1.29x + 2

• y=1.29 + 2x

• 30 = 1.29x + 2

• y = 1.29(30) + 2

A group of mountain climbers begin an expedition with 250 pounds of food. The plan to eat a total of 12 pounds of food per day. Write a linear equation to find the number of days their food will last.

• y = 250 + 12x

• y = 250 - 12x

• 0 = 250 - 12x

• y = 250 - 12(0)

pV = nRT
solve for R

• R= pV/nT

• R= p/n + V/T

• R= pV - nT

• R= (pV-n)/T

Solve -2 = 4r + s for s.

• s = -2 + 4r

• s = 2 - 4r

• s = -2 - 4r

• s = 2 + 4r
