Tomas bought 3 software apps and 2 e-books for a total of $21. The two e-books cost $12. If s represents the cost of each app, the total cost of all 5 items is represented by 3 s 12 = 21. Which statement about verifying the solution for s is true? The solution is given by s = 6 because it makes the value of 3 s 12 equal to 21. The solution is given by s = 3 because it makes the value of 3 s 12 equal to 21. The solution is given by s = 9 because it makes the value of 3 s 12 equal to 21. The solution is given by s = 12 because it makes the value of 3 s 12 equal to 21.

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
