12. Two trains, Train A and Train B, weigh a total of 312 tons. Train A is heavier than Train B. The difference in their weights is 170 tons. Use elimination to solve the system of equations to find the weight of each train. a + b = 312 a-b= 170 a + b = 312 a - b = 170
Answer:
a = 241
b = 71
Step-by-step explanation:
a + b = 312 (#1)
a - b = 170 (#2)
(#1) + (#2) = 2a = 482.
a = 482 / 2 = 241.
b = 312 - 241 = 71.

Find the unit rate. 108 people 12 days people : days = (Type whole numbers or decimals.)
108 people 12 days
the people:days=108:12
BUT this is not simplified of course
We simplify ratios like a fraction.
We can see that both numbers are divisible by 12
So we can do
108÷12/12÷12=9/1 (answer)
To know that both are divisible by 12 isn't hard as long as you are observant and are good with numbers and the divisibility rules of 2 and 3.

HELP PLEASE FAST 15 and 16 how to solve PLEASE
Answer:
15. 6
16. 40
Step-by-step explanation:
Use the formula for pythagorus: c^2 = a^2 + b^2
15. 10^2 = 8^2 + b^2
100 = 64 + b^2
*minus 64 on both sides
36 = b^2
*square root both sides
b = √36 = 6
16. c^2 = 24^2 + 32^2
c^2 = 576 + 1024
c^2 = 1600
*square root both sides
c = √1600 = 40
Hope this helps :)
1) 164
2) 1600
because a^2 + b^2 = c^2 <3
1) 3x – 2y = 2
y = 2x + 8
