Answer: £26.25
Step-by-step explanation:
10% of £25 = £2.50
Half of £2.50 = £1.25
therefore if you add £1.25 to £25 it equals £26.25
Answer:
El caso de la adición es trivial.
La adición entre los números A y B es:
A + B
Entonces la adición entre los números 43 y -32 es:
43 + (-32)
No hace falta realizar la suma para darnos cuenta de que el resultado tendra signo positivo, esto se da porque el módulo del número positivo es mayor que el del número negativo.
Así tenemos:
43 + (-32) = 43 - 32 = 11
Para el caso de la multiplicación podemos recordar:
(+)*(+) = (+)
(-)*(+) = (-)
(+)*(-) = (-)
(-)*(-) = (+)
Entonces el producto entre un número positivo y uno negativo (como es nuestro caso con 43 y -32) siempre tendrá un signo negativo.
Entonces podemos concluir que el signo de la multiplicación entre esos dos números va a ser negativo.
También podemos resolver la multiplicación de otra forma para ver esto:
43*(-32)
43*( (-1)*32)
43*(-1)*(32)
(-1)*(43*32)
Que es claramente un número negativo.
A constant is a number that stays the same no matter what any outside variables are. In this case, the variables are the number of hours of the event and the number of attendees. However, it states in the problem that the event will be 5 hours so that becomes known; the only thing that might change is the number of attendees so you can eliminate any cost that will be affected by that. You are left with Facility Rental, Musical Entertainment, and Cleaning Fee. Furthermore, you can be sure that Musical Entertainment and Cleaning Fee must be included in the constant because they are described as "flat rates", which means they do not change.
The answer is D) It is the total cost for entertainment, facility rental, and cleaning.
Hope this helps!
F(x) = 15x + 50/x + 5
y = 15x + 50/x + 5
x = 15y + 50/y + 5
x(y + 5) = 15y + 50
xy + 5x = 15y + 50
5x - 50 = 15y - xy
5x - 50 = y(15 - x)
y = 5x - 50/15 - x
SO
The inverse of f(x) = 5x - 50 over 15 - x
I think answer should be 450 please give me brainlest let me know if it’s correct or not okay thanks bye
