PLEASE HURRY Jack is training for his pilot's license. Airplane instruction costs $130 per hour, and the flight
simulator costs $65 per hour. Heller Flight School requires students to spend 6 more hours in
airplane instruction than in the simulator. If Jack can afford to spend $5655 on training, what is
the maximum number of hours of training in an airplane and in a simulator he can afford in
getting his license?
a) airplane: 31 simulator: 25
go to card 9
b) airplane: 26 simulator: 20
go to card 16
c) airplane: 25 simulator: 31
go to card 11
d)airplane: 20 simulator: 26
go to card 8
e) airplane: 30 simulator: 30
go to card 6

for the simulator, it is 390 for 6 hours and the real deal is 780 for 6 hours. I would pick the simulator because it is cheaper and you will definitely save money

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
