Answer:
-11
Step-by-step explanation:
assuming 4x-3 = f(x) and the other equation = g(x)
(4x-3) - (x^2 +2x)
(4(4)-3) - (4^2 +2(4)
(16-3)-(16+8)
(13)-(24)
-11
The factors of 66 are 1, 2, 3, 6, 11, 22, 33, and 66. Out of these factors, the greatest factor of 66. The next highest factor other than 66 is 33. A number which is three more than 33 is 33 + 3 = 36.
There is another equation to solve it simultaneously
Answer:
Adult tickets sold: 156
Step-by-step explanation:
Adult ticket: x
Student ticket: y
x + y = 260 ===> -6(x + y = 260) ===> -6x -6y = -1560
6x + 4.5y = 1404 ===> 6x + 4.5y = 1404
________________
add the two equations to eliminate a variable: -1.5y = -156
divide by -1.5: y = 104
substitution to find x:
x + y = 260
x + 104 = 260
x = 156
