Two trains, Train A and Train B weigh a total of 349 tons. Train A is heavier than Train B. The difference in their weights is 2
Ainat [17]

Answer:

Train A = 299 tons Train B = 50 tons

Step-by-step explanation:
Train A = x

Train B = y

x+y = 349

x= y +249

Plug in one equation into another

y+249+y= 349

Simplify

2y+249=349

Subtract 249 from both sides

2y=100

Divide both sides by 2

y=50

Plug it into the x equation to solve for x

x+50=349

-50 from both sides

x=299

PLS HELPPPP <br><br> 14. IF m1 = (x + 13)°<br> mz2 = 39° AND<br> mz3 = (5x + 4)º.<br> SOLVE FOR X.
forsale [732]

Answer: x=12

Step-by-step explanation:

m\angle1=(x+13)^0 \ \ \ \ \    m\angle2=39^0\ \ \ \ m\angle3=(5x+4)^0\\

The sum of the angles of the triangle is 180°:

(x+13)+39+(180-(5x+4))=180\\\\x+13+39+180-5x-4=180\\\\-4x+48=0\\\\-4x+48+4x=0+4x\\\\48=4x

Divide both parts of the equation by 4:

12=x\\\\Thus,\ x=12
