Un medico receta a un paciente tomar una pastilla cada 6 horas y un jarabe cada 8 horas. Si
Xelga [282]

Queremos ver cuando será la proxima vez que una persona <u>tome dos medicamentos al mismo tiempo</u> dado que los toma en intervalos regulares.

Veremos que luego de 24 horas el paciente volvera a tomar ambos medicamentos juntos.

Sabemos que el paciente toma una pastilla cada 6 horas y un jarabe cada 8 horas.

El paciente volvera a tomar ambos medicamentos juntos en el primer multiplo comun de 6 y 8.

Para encontrarlo podemos simplemente escribir los multiplos de cada uno y ver cual es el primero que aparece para ambos números:

6*1 = 6

6*2 = 12

6*3 = 18

6*4 = 24

y

8*1 = 8

8*2 = 16

8*3 = 24

Podemos ver que 24 es un multiplo comun (el primero) de 6 y 8.

Esto significa que luego de 24 horas el paciente volvera a tomar ambos medicamentos juntos.

A recipe for crumb cake says to mix 3/8 cup of brown sugar and 1/3 cup of white sugar. From this sugar mixture, set aside 1/4 cu
ch4aika [34]

brown sugar= \frac{3}{8}

white sugar= \frac{1}{3}

you need to mix brown sugar with white sugar

\frac{3}{8} + \frac{1}{3} = \frac{9+8}{24} = \frac{17}{24}

then it says you need to set aside 1/4 for the crumb topping from the previous sugar mixture that was  \frac{17}{24}, so

\frac{17}{24} - \frac{1}{4} = \frac{68-24}{96} = \frac{11}{24}

The sugar mixture used to make the cake is \frac{11}{24}

The perimeter is 40. How much bigger is the longest side than the shortest side?
sesenic [268]

Answer:

10

Step-by-step explanation:

40=2a<u>-3</u>+2a+3a<u>+1</u>

add like terms

  • 40=7a-2

get 'a' by its self

  • 40(+2)=7a<u>-2(+2)</u> [2 cancels out]
  • 42(÷7)=7a(÷7) [7 cancels out]
  • a=6

plug in the answer for Equations

  • biggest: 3(6)+1= 18+1= 19
  • smallest: 2(6)-3= 12-3=9

subtract smallest from biggest

  • 19-9=10
