Answer:

Mauricio nació en el año 2000.

Step-by-step explanation:

Supóngase que el cumpleaños se celebra en el año 2020, si x es la edad actual de Mauricio, entonces la expresión matemática que traduce el enunciado del problema es:

\frac{(x+13)-10}{23} +20 = 21

Ahora, se desarrolla y se simplifica la ecuación:

\frac{x+3}{23}+20 = 21

\frac{x+3}{23} = 1

Se despeja x:

x +3 = 23

x = 20

Mauricio tiene 20 años.

Ahora, el año de nacimiento de Mauricio es la sustracción de la edad de Mauricio del año actual:

y = 2020-20

y = 2000

Mauricio nació en el año 2000.

Simplify: 36÷(–3) + 2(27÷3 x -2).
jeka94

Answer:

-48

Step-by-step explanation:

36/-3 = -12

-12 + 2(27/3 * -2)

27/3 = 9

-12 + 2(9 * -2)

9 * -2 = -18

-12 + 2(-18)

2 * -18 = -36

-12 + -36 = -12 - 36

-48

The associative property of addition is pretty much just any numbers in place of these: a + (b + c) = (a + b) + c. Therefore, your answer would be d) (6 + 1) + 9 = 6 + (1 + 9)

Soon after taking an aspirin, a patient has absorbed 320 mg of the drug. after 3 hours, only 40 mg remain. find an exponential m
Anastaziya [24]
The equation will be of the form:
A(t)= A_{0} e^{rt}
where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:
40=320e^{3r}
Rearranging and taking natural logs of both sides, we get:
ln\ 0.125=3r
r=\frac{ln\ 0.125}{3}=-0.693
The required model is:
A=A _{0} e^{-0.693t}
