The lecture you were listening to is over. The bell that rang in the hall signaled the end of class. You get up out of your seat, pick up your things and walk out the classroom door. Which kind of nerves sent the signals from your brain to initiate your physical movements

i think that the best answer would be c.

tell me if im wrong : )

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

: -)

yes it is weird but true

that is true   : ) hope this you
