Answer:
24
Step-by-step explanation:
Cost of membership + game = 2.50x + 54
Cost of just games = 4.75x
The catch is, how do we make up the 54 dollars?
So equate the 2 costs
4.75x = 2.50x + 54 Subtract 2.50
4.75x - 2.50x = 54 Combine
2.25x = 54 Divide by 2.25
x = 54/2.25
x = 24
That means that 24 is the break even point.
Answer:
8x+$0.75x.
Step-by-step explanation:
8x is the hours you babysit and $0.75x the miles you drive.
Answer: 1) 96. 2) 320.
Step-by-step explanation:
Answer:
5.97
Step-by-step explanation:
If the radius of the circle = r then
pi r^2 = 56
r^2 = 56/pi
r = sqrt(56/pi)
The radius of the circle is equal to half of a diagonal of the square. That is,
r = (1/2) sqrt (2x^2)
= x (sqrt 2)/2
= x/(sqrt 2)
So x = r sqrt 2
= sqrt (56/pi) sqrt 2
= 4 sqrt (7/pi)
= 5.9708
