1/15.999=x/54.5<br> Does anyone know what to do? I keep getting the answer wrong.
kkurt [141]
Hello!

First, let's write the problem.
\frac{1}{15.999}=\frac{x}{54.5}
Let's switch sides now, otherwise, we are going to end up doing it later.
\frac{x}{54.5}=\frac{1}{15.999}
Multiply both sides by 54.5.
\frac{x}{54.5} *54.5 =\frac{1}{15.999}*54.5
We could also rewrite that as,
\frac{54.5x}{54.5}=\frac{1\cdot \:54.5}{15.999}
Simplify.
\frac{54.5x}{54.5}=x
\frac{1\cdot \:54.5}{15.999}=\frac{54.5}{15.999}
x=3.40646\dots
That would be our final answer, we could round it to.
x ≈ 3.40

You can feel free to let me know if you have any questions regarding this!
Thanks!

Heidi solved the equation 3(x + 4) + 2 = 2 + 5(x – 4). Her steps are below: 3x + 12 + 2 = 2 + 5x – 20 3x + 14 = 5x – 18 14 = 2x
Morgarella [4.7K]

Answer:

see below

Step-by-step explanation:

3(x + 4) + 2 = 2 + 5(x – 4)

Distribute using the distributive property

3x + 12 + 2 = 2 + 5x – 20

Combine like terms  (simplify)

3x + 14 = 5x – 18

Subtract 3x from each side using the subtraction property of equality

14 = 2x – 18

Add 18 to each side using the addition property of equality

32 = 2x

Divide each side by 2 using the division property of equality

16 = x

el punto (4, -3) esta sobre el lado terminal del angulo 0 en posicion normal. hallar el valor de las seis razones trigonometrica
maxonik [38]

Answer:

Para un punto (x, y), el angulo generado entre el eje x y un rayo que conecta el origen de coordenadas con el punto es tal que:

Tan(θ) = y/x

Cos(θ) = x/(√(x^2 + y^2))

Sin(θ) = y/(√(x^2 + y^2))

Y las otras 3 relaciones trigonometricas son las inversas de las de arriba, entonces:

Ctg(θ) = x/y

Sec(θ) = √(x^2 + y^2)/x

Csc(θ) = √(x^2 + y^2)/y

En este caso tenemos el punto (4, -3), es decir:

x = 4

y = -3

Solo tenemos que reemplazar esos dos valores en las seis ecuaciones de arriba:

Tan(θ) = -3/4

Cos(θ) = 4/(√(4^2 + (-3)^2)) = 4/5

Sin(θ) = -3/(√(4^2 + (-3)^2)) = -3/5

Ctg(θ) = 4/(-3) = -4/3

Sec(θ) =  √(4^2 + (-3)^2)/4 = 5/4

Csc(θ) = √(4^2 + (-3)^2)/-3 = 5/-3 = -5/3
