Billy's age is twice Joe's age and the sum of their ages is 45. How old is Billy?

Mathematics

Answer:

30 years old

Step-by-step explanation:

Joe's age can be set to x. Since Billy is twice as old as Joe, his age can be set to 2x. They add up to 45. You can set up an equation, 2x+x=45.

Simplify the equation.

3x=45, x=15

Joe is 15. Billy is 2(15)=30.

Whats 14.635 rounded to the nearest cent?
Nutka1998 [239]
The cents are .635 and the greatest cent is 6. So, when it is rounded to the greatest value like estimating it will be 14.600 or 14.6. As easy as that. :)

Need help using synthetic division! ​
viktelen [127]

Answer:

3x^{2} -3x+8-\frac{9}{x+1}

Step-by-step explanation:

Since we're dividing the polynomial by (x+1), we'll be using -1 to start the division.

Before setting the division up, let's list the coefficients of x from descending powers and the constant.

The coefficient of x^{3} is 3

Since we don't see an x^{2}, the coefficient will be 0.

The coefficient of x is 5.

Lastly, the constant, which is the term without the x is -1.

Refer to the attached picture before continuing.

After referring to the picture, we now have the coefficients for the quotient.

The coefficient of x^{2} is 3.

The coefficient of x is -3.

The constant is 8.

Lastly, since the last number is not zero, it's the remainder just like regular division. This can be tricky to remember, but -9 is not the actual remainder.

The remainder is actually \frac{-9}{x+1}.

Now putting all the pieces together, we get:

3x^{2} -3x+8-\frac{9}{x+1}

3x/2y=11 x+y/2=7 igualacion<br> Alguien me puede ayudar
bearhunter [10]

La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).

<h3>¿Cómo resolver un sistema de ecuaciones linear por igualación?</h3>

Los sistemas de ecuaciones basadas en entidades algebraicas se resuelven mediante procedimientos algebraicos. Grosso modo, el método de resolución por igualación consiste en despejar una variable en dos ecuaciones del sistema para eliminarla y reducir el número de ecuaciones <em>lineales</em> y el número de variables.

A continuación, presentamos una aplicación del método de eliminación:

\frac{3\cdot x}{2\cdot y} = 11

x = \frac{22\cdot y}{3}

x + \frac{y}{2} = 7

x = 7 - \frac{y}{2}

\frac{22\cdot y}{3} = 7 - \frac{y}{2}

\frac{47\cdot y}{6} = 7

y = 42/47

x = 7 - \frac{y}{2}

x = 308/47

La solución del sistema de ecuaciones es igual a (x, y) = (308/47, 42/47).
