If someone could answer this that would be great! I also need to find B. even if you just get me started that would be great!

train A = 374

train B = 95

Step-by-step explanation:

First, set up an equation that will help you: (x + 279) + x = 469

train A = x + 279

train B = x

To begin, subtract 279 from both sides of the equation: 2x = 190

Then divide both sides by 2: x = 95

Now plug 95 in for x on the original equation: 95 + 279 + 95 = 469

Since that is true, we have done the problem correctly.

Now plug 95 in for both the equations for train A and B:

train A = 95 + 279 = 374

train B = 95

I hope this helps!

step-by-step explanation:

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
