Question

Sam has a total of 58 DVD's and CD's. If the number of CD's is two more than three times the number of DVD's, how many CD's does he have?

42

14

44

12

Answer 1

14 is my lucky guess

Answer 2

let the no. of dvds be x.
by problem,
(2+3x)+x=58
4x=56
x=56/4
x=14.
no. of dvds=14
no. of cds=58-14=44

Answer 9

hit me with them

Answer 10

A batter hits a baseball upward with an initial speed of 96 feet per second. After how many seconds does the ball hit the ground? Use the formula h = rt − 16t2 where h represents height in feet and r represents the rate in feet per second.

Answer 11

final speed is zero.

Answer 12

i need help solving it though :/

Answer 13

The height in meters of a projectile can be modeled by h = −4.9t2 + vt + s where t is the time (in seconds) the object has been in the air, v is the initial velocity (in meters per seconds) and s is the initial height (in meters). A soccer ball is kicked upward from the ground and flies through the air with an initial vertical velocity of 4.9 meters per second. After how many seconds does it land approximately?

Answer 14

is that baseball one is 16+2 or 16*2?
