________________________________
Explanation:
_____________________________
10 + (x/6 ) = 5 ; solve for "x" ;
_____________________________
Subtract "10" from each side ;
______________________________
10 + (x/6 ) - 10 = 5 - 10 ;
______________________________
to get:
____________________________
x / 6 = -5 ;
__________________
Now, multiply EACH side of the equation by "6" ; to isolate "x" on one side of the equation; and to solve for "x" ;
______________________________
(x/6) *6 = -5 * (6) ;
_______________________________
To get: x = 30 .

Answer:
18 and 335
Step-by-step explanation:
y = 18x + 11
x * y = 6030
x * (18x + 11) = 6030
18x^2 + 11x = 6030
18x^2 + 11x - 6030 = 0
(18x + 335)(x - 18) = 0
18x + 335 = 0 x - 18 = 0
18x = -335 x = 18
x = -335/18
x is gonna have to be a positive number...so x = 18
y = 18x + 11
y = 18(18) + 11
y = 324 + 11
y = 335
so ur numbers are 18 and 335
X - 2y = - 9
7x + 2y = 1
x - 2y = - 9
(+)
7x + 2y = 1
___________
8x = - 8
x = - 1
- 1 - 2y = - 9
2y = 8
y = 4
i am a mathematics teacher. if anything to ask please pm me
35 quarts
7 x 4 = 28 days
28 x 40 = 1120
1120 ounces = 35 quarts
