Let x be the unknown amount of child tickets
Let 450 - x be the unknown amount of adult tickets (This is because the total amount subtracted from the child tickets can only be the adult tickets since there are no other tickets)
2x+5(450-x)=1800
(2x because each child ticket cost $2 and same for the adult tickets. Each adult ticket cost $5. So, the sum must be 1800.)
Simplify the equation.
2x+5(450-x)=1800 *Distribute*
2x+2250-5x=1800 *Combine like terms. (2-5=-3)*
-3x + 2250 = 1800 *Move constants and variables to opposite sides*
-2250 -2250
---------------------------
-3x=-450 *Divide by 3 to isolate the variable*
---- ------
-3 -3
x=150
So, there are 150 child tickets. To find adult tickets, just subtract children tickets from the amount of tickets bought (450-150) to get 300 adult tickets sold.
radians is equal to 90°.
Step-by-step explanation:
Step 1:
If an angle is represented in radians, it will be of the form 
radians.
If an angle is represented in degrees, it will be of the form x°.
To convert radians to degrees, we multiply the radian measure by 
.
For the conversion of radians to degrees,
the radians in degrees = (given value in radians)().
Step 2:
To convert ,
So radians is equal to 120°.
g(n) = 3n³ - 5 h(n) = 2n - 5 (g + h)(2) = g(2) + h(2)
g(2) = 3(2)³ - 5 = 3(8) - 5 = 24 - 5 = 19
h(2) = 2(2) - 5 = 4 - 5 = -1
g(2) + h(2) = 19 + -1 = 19 - 1 = 18
