Since LON is a straight angle, it equals 180 degrees. That makes LOM and MON supplementary angles. Thus, we know (7x-92) + (6x+12) = 180. Since both are positive, we can drop the parentheses.
7x - 92 + 6x + 12 = 180
Simplify: 13x - 80 = 180
Add 80 to both sides: 13x = 260
Divide both sides by 13: x = 20
Plug in: 7(20)-92
140 - 92
LOM is 48 degrees.
The answer would be 4,500 gallons left.

Answer: x = 4 , y = -3
Step-by-step explanation:
Going by the Cramer's rule , we first determine the determinant by dealing with only the coefficients of x and y in the 2 x 2 matrix.
2x - 3y = 17
5x + 4y = 8
2 -3
5 4, going by the rule now, we now have
(2 x 4) - (5 x -3)
8 + 15
= 23.
Now to find the value of x , replace the constants with the coefficient of x and divide by he determinants.
17 -3
8 4
---------------
2 -3
5 4
( 17 x 4 ) - ( 8 x -3 )
---------------------------
23
= 68 + 24
------------
23
= 92/23
= 4.
x = 4
Now to find y, just repeat the process by replacing the coefficient of y with the constants.
2 17
5 8
-----------
2 -3
5 4
( 2 x 8 ) - ( 5 x 17 )
-----------------------
23
16 - 85
---------
23
= -69/23
= -3
y = -3.

substitute for the values in any of the equations above.
2(4) - 3(-3)
8 + 9
= 17
