The total revenue that is obtained from selling the tickets is the sum of the revenue from selling the child tickets and the adult tickets. If x and y are the number of child and adult ticket, the equation that would represent the given is,
                                   4x + 6y = 420
The equation that would allow us to solve for the number of adult tickets is,
                                        6y = 420 - 4x
Simplifying,
                                         <em>y = 70 - 2x/3</em>

---------- = ---------- = 26

(1`/10)        1/10

There are 26 tenths in 2 3/5.

Can somebody help me please!!!
Effectus [21]

Answer:

Part A: 0

Part B: 0 or 1

Step-by-step explanation:

Part A: anything to the 0 power is 1 (x^0= x^y-y) if you solve 7^2 you get 49. 49^0= 1

Part B: Because it is already being raised to the power of 0, if x=0 it will remain equal to one (as explained above). Anything raised to the 1 power is itself, so 7^0= 1 and 1^1 =1

Hope this helped!
