Answer:
D = 51, other = 30
Step-by-step explanation:
d = | 5 1 |
|-1 10|
D = (5 x 10) - ( 1 x -1) = 50 + 1 = 51
| 2 4|
|-3 9|
(2 x 9) - (4 x -3) = 18 + 12 = 30
Answer:
I think it's true. hope this helps!!
Answer:
-2/3x+y=7
Step-by-step explanation:
standard is AxBy=C
so move the 2/3 over to get 7 by itself.
(-4x + 42) = (64 - 6x)
-4x + 42 = 64 - 6x
+6x on both sides
2x + 42 = 64
-42 on both sides
2x = 22
/2 on both sides
x = 11
Answer:
x = 11
