Answer:
x = s, y = t, z = 8 -s -t
Step-by-step explanation:
It can work reasonably well to let s and t represent any of a pair of the variables. In the answer above, we have used x=s, y=t.
You could get more elaborate if you want:
x = 4-s, y = 4-t, z = s+t
Answer: 
Step-by-step explanation:
We have the following function:
And we have to evaluate it when 
, this means we have to substitute 
by 
:
Solving:
Finally:
Answer: 2.3
Step-by-step explanation:
9.2 is divided by 4 is 2.3 so the last quarter is 2.3
Answer:the answer is 5/2 because if yo subtract y2 from y1 and x2 from y2 thats the answer you get.
But you might not get that answer straight away you need to simplify the initial value and keep going until you cant simplify without a remainder.
Step-by-step explanation:
