Two trains, Train A and Train B, weigh a total of 267 tons. Train A is heavier than train B. The difference of their weights is 87 tons . What is the weight of each train?

train a weighs 177 and train b weighs 90

Step-by-step explanation:

train a weighs 87 more tons than train b but both combined is 267.

a + b = 267

267 - 87 = 180

divide by two to get the weight of train b

180/2 = 90

add the 87 to find the weight of train a

90 + 87 = 177

check

90 + 90 + 87 = 267

this is my first time answering a question, hope this helped :)

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
