Two trains, Train A and Train B, weigh a ton of 484 tons. Train A is heavier than Train B. The difference of their weights is 398 tons. What is the weight of each train.

A = 441 tons

B = 43 tons

Step-by-step explanation:

Let A = weight of train A and B = weight of train B,

Given that they two trains weigh a total of 484 tons,

A + B = 484 (eq 1)

Also given that the difference of their weights is 398 tons and A is heavier than B,

A - B = 398 (eq 2)

solving the system of equations by elimination

(eq1) + (eq2):

(A + B) + (A - B) = 484 + 398

A + B + A - B = 882

2A = 882 (divide both sides by 2)

A = 882/2

A = 441 tons  (substitute this back into equation 1)

A + B = 484

441 + B = 484  (subtract 441 from both sides)

B = 484 - 441

B = 43 tons

Hope this helps!

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
