Percent means parts out of 100
x%=x/100


find change
10 to 60=50    (60-10=50)

percent change=change/originla
original=10
change=50
50/10=x%
5/1=x/100
multiply both sides by 100
500=x

answer is 500%

B. because 100% of 10 is 10, u have 60 which is 6 times that, so 100%*6 which = 600%
but it's the change, not just that, and the change is 50, so 500%

Solve the following exponential equations.<br> 10^(x+1) − 10^(x−1) = 1287
Rudiy27

Answer:x=2.114

Step-by-step explanation:

Given

10^{x+1}-10^{x-1}=1287

10\times 10^x-\frac{10^x}{10}=1287

Let 10^x=y

10y-\frac{y}{10}=1287

\frac{100y-y}{10}=1287

99y=1287\times 10

y=\frac{12870}{99}=130

10^x=130

Taking \logboth sides

x\log (10)=\log (130)

x=\frac{\log (130)}{1}

x=2.114

Completa la tabla.
Aleks [24]

La tabla completa es:

Numero      opuesto        valor absoluto.

  -5                   5                        5

   10                  -10                     10

  -56                 56                      56

  34                  -34                     34

<h3>¿Como completar la tabla?</h3>

En este caso tenemos la tabla:

Numero      opuesto        valor absoluto.

  -5

   10

  -56

  34

Para completar la tabla debemos encontrar los opuestos de esos numeros, el opuesto de cualquier numero real es un número con el mismo valor absoluto pero distinto signo, entonces podemos completar la tabla:

Numero      opuesto        valor absoluto.

  -5                   5

   10                  -10

  -56                 56

  34                  -34

Ahora debemos encontrar los valores absolutos, eso es el mismo número pero en forma positiva, completando eso obtendremos:

Numero      opuesto        valor absoluto.

  -5                   5                        5

   10                  -10                     10

  -56                 56                      56

  34                  -34                     34
