Answer:
(x, y) = (-6, 3)
Step-by-step explanation:
Maybe you want to solve ...
Use the first equation to substitute for y in the second:
2x +3(-2x -9) = -3
2x -6x -27 = -3
-4x = 24 . . . . . . . . . add 27, simplify
x = -6 . . . . . . . . . . . divide by -4
y = -2(-6) -9 = 12 -9 = 3
The solution is (x, y) = (-6, 3).
Since 57x17=969 I did 969-942 and got 27 so there is 16 full rows and then 27 left over so that means it won’t be a full row but 27 extra seats will be filled. (If your wondering where the 17 came from that’s how many rows can be made that’s over 942 because if I did 57x16 it would equal 912 and I would not have had a full row of chairs)
Answer:
- 1. Adjacent, 2. Vertical, 3. Neither
Step-by-step explanation:
1.
- The first pair is adjacent as they have common side.
2.
- The second pair is vertical as opposite angles of the crossed lines.
3.
- The third pair has no relationship with each other, so neither is the answer.
Around 1 or 2 because I calculated it
