Answer: quit
Step-by-step explanation:
Un mes Rodrigo alquiló 2 películas y 3 juegos de video con un costo total de $230.50. El próximo mes él alquiló 4 películas y 8 juegos de video con un costo total de $580.00. Hallar el costo de alquiler de cada película y de cada juego de video.
Answer:
El costo de alquiler de cada película es $26 y el costo de alquiler de cada juego de video es $59.50.
Step-by-step explanation:
A partir de la información proporcionada, puedes escribir las siguientes ecuaciones:
4x+8y=580 (1)
2x+3y=230.50 (2), donde:
"x" es el costo de alquiler de cada película y "y" es el costo de alquiler de cada juego de video.
Primero, puedes despejar x en (1):
4x=580-8y
x=145-2y (3)
Segundo, debes reemplazar (3) en (2):
2(145-2y)+3y=230.50
290-4y+3y=230.50
290-230.50=4y-3y
y=59.50
Tercero, debes reemplazar el valor de y en (3) para encontrar el valor de x:
x=145-2(59.50)
x145-119
x=26
De acuerdo a esto, la respuesta es que el costo de alquiler de cada película es $26 y el costo de alquiler de cada juego de video es $59.50.

To eliminate the y-terms and solve for x in the fewest steps, by which constants should the equations be multiplied by before adding the equations
together?
First Equation: 5x - 4y = 28
Second equation: 3x - 9y = 30
The first equation should be multiplied by 3 and the second equation by 5.
The first equation should be multiplied by 9 and the second equation by -4.
The first equation should be multiplied by 3 and the second equation by -5.
The first equation should be multiplied by 9 and the second equation by 5.
Answer:
D
Step-by-step explanation:
took the test
To eliminate the y-terms and solve for x in the fewest steps , the first equation should be multiplied by 9 and the second equation by -4.
The equation is as follows:
5x - 4y = 28
3x - 9y = 30
To eliminate the y-terms and solve for x can be done as follows:
Multiply the equation(i) by 9
45x - 36y = 252
Multiply the equation(ii) by -4
Therefore,
-12x + 36y = -120
Combine the equation45x - 36y = 252
-12x + 36y = -120
y will be eliminated by adding the equations.
Therefore, to eliminate the y-terms and solve for x in the fewest steps , the first equation should be multiplied by 9 and the second equation by -4.

−3x−9y=18
4x+3y=12
Answer:
x = 6 , y = -4
Step-by-step explanation:
Solve the following system:
{-9 y - 3 x = 18 | (equation 1)
3 y + 4 x = 12 | (equation 2)
Swap equation 1 with equation 2:
{4 x + 3 y = 12 | (equation 1)
-(3 x) - 9 y = 18 | (equation 2)
Add 3/4 × (equation 1) to equation 2:
{4 x + 3 y = 12 | (equation 1)
0 x - (27 y)/4 = 27 | (equation 2)
Multiply equation 2 by 4/27:
{4 x + 3 y = 12 | (equation 1)
0 x - y = 4 | (equation 2)
Multiply equation 2 by -1:
{4 x + 3 y = 12 | (equation 1)
0 x+y = -4 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{4 x+0 y = 24 | (equation 1)
0 x+y = -4 | (equation 2)
Divide equation 1 by 4:
{x+0 y = 6 | (equation 1)
0 x+y = -4 | (equation 2)
Collect results:
Answer: {x = 6 , y = -4

Each letter of the word "supercalifragilisticexpialidocious" is placed into a bag and drawn at 3 times, replacing the letter after each draw. Find the probability that the letter "i" is drawn at least once.
Answer:
P(X ≥ 1) = 0.50
Step-by-step explanation:
Given that:
The word "supercalifragilisticexpialidocious" has 34 letters in which 'i' appears 7 times in the word.
Then; the probability of success = 7/34 = 0.20588
Using Binomial distribution to determine the probability; we have:
[tex]P(X = x) = ^nC_x \ \beta^x \ (1 - \beta)^{n-x}[/tex]
where;
x = 0,1,2,...n and 0 < β < 1
and x represents the number of successes.
However; since the letter is drawn thrice; the probability that the letter "i" is drawn at least once can be computed as:
P(X ≥ 1) = 1 - P(X< 1)
P(X ≥ 1) = 1 - P(X =0)
[tex]P(X \ge 1) = 1 - \bigg [ {^3C__0} (0.21)^0 (1-0.21)^{3-0} \bigg][/tex]
[tex]P(X \ge 1) = 1 - \bigg [ 1 \times 1 (0.79)^{3} \bigg][/tex]
P(X ≥ 1) = 1 - 0.50
P(X ≥ 1) = 0.50

Answer:
x = √75
Step-by-step explanation:
We can write out all relations of each triangle here using the Pythagorean theorem (there are 3 triangles total). The triangles are ABD, BCD, and ABC.
For triangle ABD:
AB² = AD² + BD²
AB² = (AC - DC)² + BD²
y² = (15 - 5)² + BD²
y² = 100 + BD²
For triangle BCD:
x² = BD² + 5²
x² = BD² + 25
For triangle ABC:
15² = x² + y²
225 = x² + y²
From here we can substitute into the equation ABC. We can substitute x² and y² with our first and second equations.
225 = BD² + 25 + 100 + BD²
225 = 2BD² + 125
100 = 2BD²
50 = BD²
We don't need to solve for BD, we can substitute it into our equation for triangle BCD to solve for x.
x² = BD² + 25
x² = 50 + 25
x² = 75
x = √75

LIVING ROOM Maude's living room is in the shape of a rectangle. Its dimensions are 21 feet by 14 feet. Find the length of the diagonal of the living room. Round your answer to the nearest tenth if necessary.
Answer:
25.2 feets
Step-by-step explanation:
Given that:
Rectangular shaped living room has the dimension:
21 feets by 14 feets
Length of diagonal :
Using Pythagoras :
A² = B² + C²
Diagonal² = 21² + 14²
Diagonal = √(441 + 196)
Diagonal = √637
Diagonal = 25.238
Diagonal = 25.2 feets ( nearest tenth)
