Answer:

−1.25 or -5/4

Step-by-step explanation:

Equation

19/24 = -5/6x - 1/4

first swap sides so that all variable terms are on the left hand side

-5/6x - 1/4 = 19/24

add 1/4 to both sides.

-5/6x = 19/24 + 1/4

Least common multiple of 24 and 4 is 24. Convert 19/24 and 1/4 to fractions with a denominator of 24.

-5/6x = 19/24 + 6/24

Since 19/24 and 6/24 have the same denominator, add them by adding their numerators.

-5/6x = 19+6/24

Add 19 and 6 to get 25

-5/6x = 25/24

Multiply both sides by -6/5, the reciprocal of -5/6

x = 25/24 (-6/5)

Multiply 25/24 times -6/5 by multiplying numerator times numerator and denominator times denominator.

x = 25(-6) / 24x5

Do the multiplications in the fraction 25(-6) / 24x5

x = -150/120

Reduce the fraction -150/120 to the lowest terms by extracting and canceling out 30

x = -5/4

With verification

First write the equation and our value for x

19/24 = -5/6x - 1/4

x = -5/4

swap sides so that all variable terms are on the left hand side

-5/6x - 1/4 = 19/24

convert -5/6x to have the same denominator of 19/24.

-5 (4)

-6 (4)

== -20/24x

write the full equation with the converted variable

-20/24x - 1/4 = 19/24

Convert 1/4 to have the same denominator of 19/24

1 (6)

4 (6)

== 6/24

write the full equation with the converted variable and retain the minus sign

-20/24x - 6/24 = 19/24

write our value of X

-5/4

convert x to have the same denominator of -20/24x

-5(6)

-4(6)

= -30/24

x = -30/24

replace x in -20/24x with our updated value of x

-20/24(-30/24)

Multiply -20/24 by -30/24

= 25/24

write the full equation

25/24 - 6/24 = 19/24

subtract 25/24 by 6/24

19/24 = 19/24

the fraction 19/24 is equal to 19/24

Answer:

Fractions are equal when one fraction can be obtained from the other.

Step-by-step explanation:

equality means a relationship between two quantities or, more generally two mathematical expressions, asserting that the quantities have the same value, or that the expressions represent the same mathematical object.

Step-by-step explanation:

Answer: Length - 40 cm, Width - 6cm

Step-by-step explanation:

Let the length of the rectangle = 20x.

Then, the width of the rectangle must = 3x by the ratio given.

The area of a rectangle is the length*width, which we are given as 240.

Therefore, 20x*3x = 240

We can combine like terms:

60x^2 = 240

Divide both sides by 60:

x^2 = 4

Square root both sides:

x = ± 2.

Since the sides of a rectangle cannot be negative, x must equal to 2.

The length of the rectangle is 20x, which is 20*2 = 40.

The width of the rectangle is 3x, which is 3*2 = 6.

What is the real- world meaning of the first equation?

The first equation is: 2x+3y=13.50

[tex]\rule{300pt}{1pt}[/tex]

Solve this system of equations using the substitution method.

[tex] 2x + 3y = 13.50 \\ 3x + 2y = 16.50[/tex]

[tex]2x + 3y = 13.50 \\ x = 5.5 - \frac{2}{3} y[/tex]

[tex]2(5.5 - \frac{2}{3} y) + 3y = 13.50[/tex]

[tex]y = 1.5[/tex]

What are the prices of adult and student tickets?

Answer:

tan²Θ

Step-by-step explanation:

simplify the expression using the identities

secΘ = [tex]\frac{1}{cos0}[/tex]

tan²Θ = sec²Θ - 1

then

[tex]\frac{cos0-cos^30}{cos^30}[/tex] ( divide each term on the numerator by cos³Θ

= [tex]\frac{cos0}{cos^30}[/tex] - [tex]\frac{cos^30}{cos^30}[/tex]

= [tex]\frac{1}{cos^20}[/tex] - 1

= sec²Θ - 1

= tan²Θ

Answer:

[tex]\tan^2(\theta)[/tex]

Step-by-step explanation:

Assuming this is

[tex]\dfrac{\cos(\theta)-cos^3(\theta)}{cos^3(\theta)}[/tex]

Trig identities used:

[tex]\sin^2(\theta)+\cos^2(\theta)=1 \implies 1-\cos^2(\theta)=\sin^2(\theta)[/tex]

[tex]\dfrac{\cos(\theta)-cos^3(\theta)}{cos^3(\theta)}[/tex]

[tex]=\dfrac{\cos(\theta)(1-cos^2(\theta))}{cos^3(\theta)}[/tex]

[tex]=\dfrac{1-cos^2(\theta)}{cos^2(\theta)}[/tex]

[tex]=\dfrac{sin^2(\theta)}{cos^2(\theta)}[/tex]

Veremos que la velocidad un minuto despues es 1,200 m/s.

Sabemos que la aceleración del cohete es constante, y es de 20 m/seg^2 (asumimos que el cohete tiene esta aceleración teniendo en cuenta la aceleración gravitatoria, es decir, 20m/seg^2 es la aceleración neta).

a(t) = 20m/seg^2.

Para obtener la velocidad, integramos la cantidad de arriba:

v(t) = (20 m/seg^2)*t + V

Donde V es la velocidad inicial del cohete, que sabemos es igual a cero.

v(t) = (20 m/seg^2)*t.

Con esta ecuación, podemos ver que la velocidad un minuto despues será:

v(60s) = (20 m/seg^2)*60s = 1,200 m/s.

I believe answer would be B

Step-by-step explanation:

I put the equation into desmos and B looks like the answer.

The graph of the polar curve r = 1 + sinФ is shown.

A form created using the polar coordinate system is called a polar curve. Points on polar curves have varying distances from the origin (the pole), depending on the angle taken off the positive x-axis to calculate distance.

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
r = 1 + sin(θ)
Using formula ,
r = a±bsinФ

Where,
a > 0 and b >0
and a = b
graph the cardioid.
r = 1 - sinФ

Thus, the graph of the polar curve r = 1 + sinФ is shown.
