Answer:

$x = 2$

Step-by-step explanation:

First we must add 4 to both sides.

$-2 = -4 + x$

+4 +4

-4 + 4 = 0

-2 +4 = 2

Isolating a variable means that it is alone on its side of the eqation.

$2 = x$

x is now isolated and we also have the solution for it.

$x = 2$

Answer:

$\frac{x}{y}=1.3$

Step-by-step explanation:

<u>Informação recuperada:</u>

(UFRGS) Se 10x = 20y , atribuindo 0,3 para log 2 , então o valor de x/y é

1) Primeiro, passando o 10 para o 2º membro como base do logaritmo:

$10x=20y \Rightarrow x=log_{10}20y$

2) Aplicando a propriedade do produto de logaritmo:

$log(AB)= logA+logB$

$x=log_{10}20y \Rightarrow x=log(2+10)y\Rightarrow x=(0.3+1)y \Rightarrow x=1.3y$

3) Como quero o quociente divido ambos os lados por y

$\frac{x}{y}=\frac{1.3y}{y}\Rightarrow \frac{x}{y}=1.3$

Citrus2011 [14]

Answer:

Mia spent 68 dollars.

Step-by-step explanation:

The equation would be 2(13.50) + 4(10.25) = x

Solving for the first part, you get 27 for adult tickets and 41 for the children tickets. When you add the two values, you get 68.

A(1)=20 <br> a(n)=a(n−1)−17 <br> Find the 3rd term in the sequence

Alexxx [7]

Answer: The third term is -14

----------------------------------------------

Explanation:

First term = A(1) = 20, which is given

Second term
A(n) = A(n-1) - 17
A(2) = A(2-1) - 17
A(2) = A(1) - 17 .... note: second term = (first term) - 17
A(2) = 20 - 17
A(2) = 3

Third term
A(n) = A(n-1) - 17
A(3) = A(3-1) - 17
A(3) = A(2) - 17 ... note: third term = (second term) - 17
A(3) = 3 - 17
A(3) = -14
