Un adulto cuya masa de 8kg camina con una rapidez de 130 cm/s​

if you need distance then

Step-by-step explanation:

speed = distance /time

so

135=x/8

135x8=x

1080=x = distance

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

step-by-step explanation:

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
