During a physics experiment, a student determines that the unit rate for a marble’s motion is 2 centimeters per second. What is the unit rate describing the number of seconds it takes the marble to travel one centimeter?

A. 1/2 second/1 centemeter

B. 2 sec/1 centemeter

C. 1/4 sec/1 centemeter

D.4 sec/ 1 centemeter

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
