Which of the following is a solution to the equation ¾x-12=-18?

4.5
-22.5
-40
-8

Answers

Answer 1

[tex]\frak{Hi!}[/tex]

[tex]\orange\hspace{300pt}\above2[/tex]

                     We have the equation [tex]\large\boldsymbol{\sf{\displaystyle\frac{3}{4}x-12=-18}}[/tex].

                     First we should add 12 to both sides of the equation.

                     [tex]\large\boldsymbol{\sf{\displaystyle\frac{3}{4}x=-18+12}}[/tex]. Simplify

                    [tex]\large\boldsymbol{\sf{\displaystyle\frac{3}{4}x=-6}}[/tex].

                   This done, let's multiply the equation by 4. You'll see why

                   [tex]\large\boldsymbol{\sf{\displaystyle\frac{3}{\not4}x\times\not4=-6\times4}}[/tex]

                   Did you see how on the left, the 4's cancelled? That's

                   because dividing by 4 and then multiplying the same

                   number, or the result, by 4, are operations that undo each

                   other.

                   This being said, let's finish solving this equation in terms of x

                   [tex]\large\boldsymbol{\sf{3x=-24}}[/tex]. See how this works?

                  Now, remember that we ought to use inverse operations

                  to solve for x. These are operations that undo each other.

                  So if x is multiplied by 3, we should... divide by 3!

                  Also, please keep in mind that we can only divide the left side

                  by 3 if we divide the right side by 3.

                 [tex]\large\boldsymbol{\sf{\displaystyle\frac{3x}{3}=\displaystyle\frac{-24}{3}}}[/tex]. Once again the 3s on the left cancel, leaving

               x. Wait! Isn't that what we wanted? Yepp, sure!

               The right side is now -8. Thus,

               [tex]\large\boldsymbol{\sf{x=-8}}[/tex]

O 12[(g+y)x 2]

Answers

Por definición de perímetro y considerando el cambio de unidades, el perímetro de la caja en pulgadas es 12[(g+y)×2].

Definición de perímetro

El perímetro de un figura geométrica plana se denomina a la longitud de su contorno. El perímetro es, por tanto, una medida de longitud.

En otras palabras, el perímetro de una figura de dos dimensiones es la distancia alrededor de la figura y es el resultado de la suma de los lados de una figura geométrica plana. Por lo que para el cálculo del perímetro es necesario conocer el número de lados de la figura y la longitud de cada uno de esos lados.

Perímetro de una caja

Una caja se puede considerar como una figura que tiene cuatro lados con dos medidas diferentes (alto y ancho).

El alto de la caja es "y" mientras que su ancho es "g" pies, por lo que su perímetro P es calculado como:

P= 2g + 2y= 2×(g+y) pies

Luego, se puede aplicar la siguiente regla de tres para realizar el cambio de unidades a pulgadas: si 1 pies equivale a 12 pulgadas, 2×(g+y) pies equivales a cuantas pulgadas?

[tex]P=\frac{2x(g+y) piesx12 pulgadas }{1 pie}[/tex]

Resolviendo

P= 12[(g+y)×2] pulgadas

Finalmente, el perímetro de la caja en pulgadas es 12[(g+y)×2].

A 10-year annuity pays $1,850 per month, and payments are made at the end of each month. If the APR is 12 percent compounded monthly for the first five years, and APR of 8 percent compounded monthly thereafter, what is the value of the annuity today?

Answers

Based on the amount the annuity pays per month and the APR, the value of the annuity today is $133,349.85.

What is the present value of the annuity?

First, find the present value of the annuity at 5 years:

= 1,850 x present value interest factor of annuity, 60 months, 8/12%

= 1,850 x 49.32

= $91,242

Then find the present value of the annuity from 5 years till date:

= (1,850 x present value interest factor of annuity, 60 months, 12/12%) + ( 91,242) / (1 + 1%)⁶⁰)

= (1,850 x 44.955) +  ( 91,242) / (1 + 1%)⁶⁰)

= $133,349.85

According to​ statistics, a person will devote 34 years to sleeping and watching TV. The number of years sleeping will exceed the number of years watching TV by 22. Over the​ lifetime, how many years will the person spend on each of these​ activities?

Answers

Considering the definition of an equation and the way to solve it, a person will devote 28 years watching TV and 6 years sleeping.

Definition of equation

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.

The members of an equation are each of the expressions that appear on both sides of the equal sign while the terms of an equation are the addends that form the members of an equation.

The solution of a equation means determining the value that satisfies it. In this way, by changing the unknown to the solution, the equality must be true.

To solve an equation, keep in mind:

When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.

This case

Being "x" the number of years watching TV, and knowing that:

The number of years sleeping will exceed the number of years watching TV by 22.A person will devote 34 years to sleeping and watching TV.

the equation in this case is:

x + (x+22) =34

Solving:

x + x =34 -22

2x= 12

x= 12 ÷ 2

x=6

As the number of years sleeping will exceed the number of years watching TV by 22, then x +22= 6 +22= 28 years.

Finally, a person will devote 28 years watching TV and 6 years sleeping.
