Step-by-step explanation:
Una escuela compró varios ejemplares del libro A, que cuesta $200.00, y del libro B, que cuesta $150.00. Compró en total 120 libros y pagó $20,500.00 por ellos. ¿Cuántos ejemplares de cada libro compró
Responder:
Copias del libro A = 50
Copias del libro B = 70
Explicación paso a paso:
Costo por libros A = 200
Costo por libro B = 150
Sea el número de libros A = x
Número de libros B = y
Número total de libros comprados = 120
Costo total = 20,500
x + y = 120 - - - (1)
200x + 150y = 20500 - - - (2)
De 1)
x = 120 - y
Sustituya x = 120-y en (2)
200 (120 - años) + 150y = 20500
24000 - 200y + 150y = 20500
24000 - 50y = 20500
-50 años = 20500 - 24000
-50y = - 3500
y = 70
x = 120 - y
x = 120 - 70
x = 50
Solve 6x2 – 2x + 1 = 0) using the Quadratic Formula.
Answer:
decimal form
x = 6.5
exact form
x = 13/2
mixed number form
x = 6 1/2
For the given quadratic equation 6x² – 2x + 1 = 0, the value of x will be 1/6+i√5/6 and 1/6-i√5/6.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation. The quadratic formula, using square roots, factoring, and completing the square are the four ways to solve a quadratic equation.
It is given that the quadratic equation is,
6x² – 2x + 1 = 0
Apply arithmetic operations in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
[tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:6\cdot \:1}}{2\cdot \:6} \\\\\ \\\ x_{1,\:2}=\frac{-\left(-2\right)\pm \:2\sqrt{5}i}{2\cdot \:6} \\\\\\\ x_1=\frac{-\left(-2\right)+2\sqrt{5}i}{2\cdot \:6},\:x_2=\frac{-\left(-2\right)-2\sqrt{5}i}{2\cdot \:6}\\\ \\\\x=\frac{1}{6}+i\frac{\sqrt{5}}{6},\:x=\frac{1}{6}-i\frac{\sqrt{5}}{6}[/tex]
Thus, for the given quadratic equation 6x² – 2x + 1 = 0, the value of x will be 1/6+i√5/6 and 1/6-i√5/6.

What is the value of x ?
Find the value of x and y
Please help me. Thank you
Answer:
Step-by-step explanation:
let each angle=A
A+A+A=180
3A=180
A=180/3=60°
as the angles are equal so sides are equal.
16+y=46
y=46-16=30
applying sine formula
[tex]\frac{30}{sin z} =\frac{46}{sin~80} \\sin~z=\frac{30}{46} \times ~sin~80=\frac{15}{23} \times sin ~80\\z=sin^{-1}( \frac{15}{23} \times sin ~80) \approx~39.96^\circ \approx40^\circ[/tex]
z+x=60
40+x=60
x=60-40=20°

7. Diane flew home from vacation with a heavy bag. With the first airline she 1 point
flew, Diane had to pay $14 to check her bag, plus $26 for every kilogram
that her bag was over the weight limit. The next flight was with another
airline that had the same weight limit. Diane had to pay $9 per kilogram
that her bag was over the weight limit, in addition to the checked bag fee
of $31. By coincidence, the fees ended up being the same with both
airlines. Write a system of linear equations to represent the situation. *

Step-by-step explanation:
Find the value of the variable that results in congruent triangles for numbers 6 and 8.
Answer:
x = 28
Step-by-step explanation:
From the figure attached,
AC ≅ FH [Given]
BC ≅ GH [Given]
AB ≅ FG [Given]
ΔABC ≅ ΔFGH [By SSS property of congruence]
Since, m∠A + m∠B + m∠C = 180°
50° + 69° + m∠C = 180°
119° + m∠C = 180°
m∠C = 180° - 119°
m∠C = 61°
m∠C = m∠H [Since, ΔABC ≅ ΔFGH]
(2x + 5)° = 61°
2x = 61 - 5
2x = 56
x = 28

In the figure shown, what additional information is needed to show that △ABC≅△DEF by ASA?
Enter your answers in alphabetical order.
Answer:
The additional information to show ΔABC ≅ ΔDEF by ASA is [tex]\overline {AB}[/tex] ≅ [tex]\overline {DE}[/tex]
Step-by-step explanation:
The given parameters in the figure are;
Angle m∠BAC is congruent to angle m∠FDE
Angle m∠ABC is congruent to angle m∠FED
Therefore, in order to show that ΔABC is congruent to ΔDEF, by the Angle-Side-Angle (ASA) rule of congruency, the additional information is the congruency of the included sides between the given angles as follows;
The additional information to show ΔABC ≅ ΔDEF by ASA is [tex]\overline {AB}[/tex] is congruent to [tex]\overline {DE}[/tex] which can be written as [tex]\overline {AB}[/tex] ≅ [tex]\overline {DE}[/tex].

What is the y-intercept of the line y + 6 = -4(X - 1.5)
Answer:
y=0.
y + 6 = -4(X - 1.5)
y+6 = -4x+6
y = mx+b
y=4x
There isn't a b, which is the y intercept, so the y int would be 0

Jerry gets price quotes from two different pool cleaning services for the cost of cleaning the pool. Company A charges $7 plus an additional $3 per hour. Company B charges $10 plus an additional $2 per hour. The total price quote for each company is the same amount. How many hours do the companies estimate it will take to clean the pool?
Answer:
3 hoursStep-by-step explanation:
Step one:
given data
price quotes from Company A
charges= $7
additional charges per hour= $3
let the number of hours be x
and the total be y
the linear function for the total is
y=3x+7
price quotes from Company B
charges= $10
additional charges per hour= $2
let the number of hours be x
and the total be y
the linear function for the total is
y=2x+10
if the total quote is the same , then
3x+7=2x+10
solve for x, collect like terms
3x-2x=10-7
x=3 hours

To get into the carnival, it costs $5. Then each ride costs $2.25. *Use a linear equation to solve the following:
If you brought $35, how many rides can you go on?
How much would it cost altogether to ride 7 rides?
Answer:
equation: y=2.25x+5
a: 13 rides
b:$20.75 for 7 rides
explanation:
a: 35=2.25x+5
first subtract 5 from 5 and 35
30=2.25x
divide each side by 2.25
x= 13 1/3
can only go on 13 rides
b: y=2.25(7)+5
2.25×7=15.75
15.75+5=20.75
$20.75 for 7 rides
Camilla is creating gift baskets with scented soaps and bottles of bubble bath. She has 20 scented soaps and 15 bottles of bubble bath. If she wants all the gift baskets identical without any items left over, what is the greatest number of gift baskets Camilla can make?
Answer:
5 gift baskets
Step-by-step explanation:
We solve this question using the method of Greatest Common Factor
We are told in the question that She has 20 scented soaps and 15 bottles of bubble bath
Hence, we find the factors of 15 and 20
The factors of 15 are: 1, 3, 5, 15
The factors of 20 are: 1, 2, 4, 5, 10, 20
Then the greatest common factor is 5.
Hence, the greatest number of gift baskets Camilla can make is 5 gift baskets
