Trains Two trains, Train A and Train B, weigh a total of 479 tons. Train A is heavier than Train B. The difference of their weights is 403 tons. What is the weight of each train?
Train A weighs
tons.

train A is 403

and train B is 72

because if the total weight is 479 and train A is heavier than train B with a difference of 403 to get their weights each, you'll say 479( total amount of weight) - 403( the difference) which or = 72...

where you have A as 403 and B as 72

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
