It was 65 degrees by lunch time.
Answer:
91 used
65 new
Step-by-step explanation:
7 + 5 = 12
156/12 = 13
7(13) = 91
5(13) = 65
There is no solution for the first one
if you eliminate y you get 2 equations
-13x - 13z = -25
-13x - 13x = -15
- there is no solution to theses
a23 means the element in the second row and the 3rd column
so its -5
8. It is a function, the x’s do not repeat
9. It is not a function, -3 is listed twice
