Answer:
84
Step-by-step explanation:
Let's say Nick gets amount N, Angad amount A, and June amount J.
Here's what we know:
A+N+J=140
A=2*N
N=3*J.
Let's plug these values in.
N=3*J, so A+N+J=140 can now be A+3*J+J=140.
A=2*N, and N=3*J, so A=2*3*J=6*J. Then, A+3*J+J=140 is now 6*J+3*J+J=140, so 10*J=140 and J=14. N = 3*J=42 and A=2*N=84. Checking this, 14+42+84=140, so we are good to go!
No it is not a function, because a function cannot have more than one output per input. When x=-3, there are two solutions shown: (-3,2) and (-3,3), therefore it cannot be a function.
