Answer:
Train A = 214
Train B = 86
Step-by-step explanation:
a + b = 300
a - b = 128
a + b = 300
a = 128 + b
(128 + b) + b = 300
128 + b + b = 300
128 + 2b = 300
2b = 300 - 128
2b = 172
b = 172 ÷ 2
b = 86
a = 128 + b
a = 128 + (86)
a = 214
The answer to this Question is A
What is Absolute Value Function or so called Modulus Function or Mod function?
It is a function that takes all real values as input and returns same values but +ve in nature eg if you give input as 2, output will be 2 and if you give input as -2, you will get output 2 again
Solution:
We have expression Ix-5I + 2
we know that I anything I , called as mod of anything, is always greater than or equal to zero so if we take its minimum value as 0 and we get 0 + 2 = 2
means this expression cant be less than 2 hence it will be greater than or equal to 2
because minimum value of mod is 0 and we are adding 2 to it hence overall the expression will be greater than 2 only

Answer:
The answer is
Step-by-step explanation:
X=29 and y=10
You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.
