Durante una venta de liquidación, el Sr. Pablo, un profesor particular, compró un total de 12 libros de asesoría de Secundaria 4 y Secundaria 1 por S/82. El precio de un libro de asesoría de Secundaria 4 era de S/ 8 y el precio de un libro de asesoría de
Secundaria 1 era de S/ 6. Que el número de los libros de asesoría de Secundaria 1 comprados sea “k”.
a) Expresa el número de libros de asesoría de Secundaria 4 comprados en términos de “k”.
b) Forma una ecuación en “k' y resuélvela, calculando la cantidad de libros de cada tipo que compró el Sr.Pablo
Resolviendo un sistema de ecuaciones, vemos que se venden 6 libros de secundaria 4 y 6 libros de secundaria 1.
¿Como escribir un sistema de ecuaciones?
Primero definimos dos variables:
x = numero de libros de secundaria 4 vendidos.k = número de libros de secundaria 1 vendidos.Sabemos que se venden 12 libros en total, entonces:
x + k = 12
Tambien sabemos que se recauda un total de $82, entonces:
x*$8 + k*$6 = $82
Entonces tenemos dos ecuaciones.
a) Usando la primer ecuacion, podemos aislar x para tener:
x = 12 - k
b) Ahora podemos reemplazar eso en la otra ecuación para solucionar el sistema.
(12 - k)*$8 + k*$6 = $82
$96 - $2*x = $82
$2*x = $12
x = $12/$2 = 6
Es decir se venden 6 libros de secundaria 4, y como se venden 12 libros en total, los otros 6 libros vendidos son de secundaria 1.

Explain when the solution set of an inequality will be the empty set or the set of all real numbers. Show an example of each.
Answer:
There are two cases when the solution set of an inequality will be the empty set or the set of all real numbers.
The first case is when the inequality is always false no matter what value is chosen for the variable. For example, the inequality x > 5 has no solution because there is no value of x that is greater than 5. In this case, the solution set is the empty set.
The second case is when the inequality is always true no matter what value is chosen for the variable. For example, the inequality x > -∞ has infinitely many solutions because there is no value of x that is not greater than -∞. In this case, the solution set is the set of all real numbers.

For the following exercises, solve each inequality and write the solution in interval notation.
30. 2| v − 7 | − 4 ≥ 42
Answer:
The solution to the inequality [tex]$2|v-7|-4 \geq 42$[/tex] in interval notation is given by [tex]$-16 \leq v \leq 30$[/tex].
Step-by-step explanation:
An absolute value inequality [tex]$2|v-7|-4 \geq 42$[/tex] is given.
It is required to solve the inequality and write the solution in interval form.
To write the solution, first solve the given absolute value inequality algebraically and then write it in interval notation.
Step 1 of 4
The given absolute value inequality is [tex]$2|v-7|-4 \geq 42$[/tex].
Add on both 4 sides,
[tex]$$\begin{aligned}&2|v-7|-4 \geq 42 \\&2|v-7|-4+4 \geq 42+4 \\&2|v-7| \geq 46\end{aligned}$$[/tex]
Step 2 of 4
Divide by 2 on both sides,
[tex]$$\begin{aligned}&\frac{2|v-7|}{2} \geq \frac{46}{2} \\&|v-7| \geq 23\end{aligned}$$[/tex]
The inequality can be written as [tex]$v-7 \leq 23$[/tex] and [tex]$v-7 \geq-23$[/tex]
Step 3 of 4
First solve the inequality, [tex]$v-7 \leq 23$[/tex].
Add 7 on both sides,
[tex]$$\begin{aligned}&v-7 \leq 23 \\&v-7+7 \leq 23+7 \\&v \leq 30\end{aligned}$$[/tex]
Step 4 of 4
Solve the inequality [tex]$v-7 \geq-23$[/tex].
Add 7 on both sides,
[tex]$$\begin{aligned}&v-7 \geq-23 \\&v-7+7 \geq-23+7 \\&v \geq-16\end{aligned}$$[/tex]
The solution of the inequality in interval notation is given by [tex]$-16 \leq v \leq 30$[/tex].

are they no solution or infinite solutions?
I'm getting ready for high school so I'm reviewing 8th grade math.
Answer:
1. No.
2. Yes, there is no solution here.
Step-by-step explanation:
The former:
[tex]8(5x - 3) = 6(-3x - 4); \\ 8 * 5x - 8 * 3 = 6 * (-3x) - 6 * 4; \\ 40x - 24 = -18x - 24; \\ 40x + 18x = -24 + 24; \\ 58x = 0; \\ x = 0.[/tex]
[tex]\{0\}[/tex] is our set of solutions.
The latter:
[tex]3x - 13 = 7(x + 2) - 4(x - 7); \\ 3x - 13 = 7x + 7 * 2 - 4x - 4 * (-7); \\ 3x - 13 = 7x + 14 - 4x + 28; \\ 7x - 4x - 3x = -13 - 14 - 28;\\ 0x = 55; \\ x \in \emptyset.[/tex]
In other words, there is not any solution from the set of real numbers that suits us.

How to solve for EF?To do this, we make use of the following law of sines
EF/sin(D)= DE/sin(F)
So, we have:
EF/sin(75)= 3/sin(50)
This gives
EF = sin(75) * 3/sin(50)
Evaluate the product
EF = 3.8

The cost of a gallon of gas increased from $3.54 to $3.87 over the weekend. What is the percent increase for the cost of gas, rounded to the nearest whole percent?
Answer:
9%
Step-by-step explanation:
percent increase is calculated as
[tex]\frac{increase}{original}[/tex] × 100%
increase = $3.87 - $3.54 = $0.33 , then
% increase = [tex]\frac{0.33}{3.54}[/tex] × 100% ≈ 9% ( to the nearest whole percent )
Answer:
9 % (rounded to the nearest whole percent)
Step-by-step explanation:
the amount of increase:
3.87 - 3.54 = 0.33
Then
the percent increase for the cost of gas :
[tex]=\frac{0.33}{3.54} \times 100\\\\= 0.093220338983 \times 100\\\\=9.3220338983 \ \%[/tex]

424. House Paint April wants to paint the exterior of her house. One gallon of paint covers about 350 square feet, and the exterior of the house measures approximately 2000 square feet. How many gallons of paint will she have to buy?
Answer:
If the exterior of the house is 2000 square feet and each gallon of paint covers 350 square feet.
Then she needs to buy 6 gallons of paint.
Step-by-step explanation:
Dividing the total area by the area that each gallon of paint covers we get,
[tex]$\frac{2000}{350} \times \frac{50}{50}=\frac{40}{7}$$[/tex]
Now, performing long division we get,
[tex]$7\overset{5}{\overline{\left){\begin{align} & 40 \\ & \underline{35} \\ & \underline{05} \\ \end{align}}\right.}}$$[/tex]
She needs five gallons of paint fully and some amount of the sixth gallon because we get a remainder.
She can't buy paint in fraction, hence she has to buy 6 gallons of paint.
