The department store sells logo t-shirts at an original price of $12.50. Every month that a t-shirt doesn’t sell, the store reduces the price by 25%. Brianna calculated the price after two reductions:

12 dollars and 50 cents minus (12 dollars and 50 cents) (0.25) minus (12 dollars and 50 cents) (0.25) = 6 dollars and 25 cents

What is Brianna’s error?

Answers

Answer 1

Answer:

Brianna subtracted $12.50, even though you are not supposed to do that to find the price. You have to subtract $6.50, not $12.50.

The final answer is $7.04 because you subtract two initial prices.

Hope this helps you!

Answer 2

Answer:

The sample answer is :Brianna took both 25% discounts off the original amount. The second discount should have been calculated on the first reduced price of $9.38. The final sale price should have been $7.03.

x + y = -10 in slope intercept form

Answers

Step-by-step explanation:

Hey there!

Given;

x+y= -10

We know that slope intercept equation form of straight line is; y = mx+c.

So, let's try to convert it into that form.

Shift"X" in Right side.

y = -x-10

Therefore, y = -x-10.

A system of linear equation could only have 1 solution. This is because the straight lines will only have to meet, cross, or intersect each other once.

A festival charges $3 for child admission and $5 for adult admision. At the end of the festival they have sold 779 tickets for a total of $2771. Set up and solve a system of equations to find how many child tickets and how many adult tickets were sold.

Answers

Answer:

562 child tickets were sold

217 adult tickets were sold

Step-by-step explanation:

A festival charges $3 for children admission and $5 for adult admission

At the end of the festival they have sold a total number of 779 tickets for $2771

Let x represent the child ticket

Let y represent the adult ticket

x + y= 779..............equation 1

3x + 5y= 2771..........equation 2

From equation 1

x + y = 779

x= 779 -y

Substitute 779-y for x in equation 2

3x + 5y= 2771

3(779-y) + 5y= 2771

2337 - 3y + 5y= 2771

2337 +2y= 2771

2y= 2771 -2337

2y = 434

y = 434/2

y = 217

Substitute 217 for y in equation 1

x + y= 779

x + 217= 779

x = 779-217

x= 562

Hence 562 child tickets were sold and 217 adult tickets were sold

Guadalupe fue a la mercería a comprar 15.5 m de encaje blanco que necesita para la clase de costura. Si cada metro cuesta $5.60, ¿cuánto pagó por todo el encaje que necesita?

También pidió 4.75 m de cinta azul que le encargó su mamá. Si el metro cuesta $8.80 y su mamá le dio $40.00, ¿le alcanzará el dinero para comprarla?

¿Le falta o le sobra dinero? ¿Cuánto?​

Answers

Answer:

a) Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.

b) Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.

Step-by-step explanation:

a) Tras una lectura cuidadosa al enunciado, establecemos que el coste total pagado por Guadalupe es el producto de metraje comprado ([tex]n[/tex]), medido en metros, y el coste unitario ([tex]c[/tex]), medido en pesos por metro:

[tex]C = c\cdot n[/tex] (Eq. 1)

Si conocemos que [tex]c = 5.60\,\frac{\$}{m}[/tex] y [tex]n = 15.5\,m[/tex], entonces tenemos que:

[tex]C = \left(5.60\,\frac{\$}{m}\right)\cdot (15.5\,m)[/tex]

[tex]C = \$ \,86.8[/tex]

Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.

b) El coste total de la cinta azul es: ([tex]c = 8.80\,\frac{\$}{m}[/tex], [tex]n = 4.75\,m[/tex])

[tex]C = \left(8.80\,\frac{\$}{m} \right)\cdot (4.75\,m)[/tex]

[tex]C = \$\,41.8[/tex]

Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.

What is the slope of the line that passes through the points (-3, -3)(−3,−3) and (-18, -23) ?(−18,−23)? Write your answer in the simplest form.

Answers

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

To find the slope of linear functions using two points, we have the following equation :

[tex]slope = \frac{y(b) - y(a)}{ x(b) - x(a) } \\ [/tex]

Where a and b are two point of the function.

_________________________________

Step (2)

Well now I want to choose a name for the given points :

a = ( -3 , -3 ) b = ( -18 , -23 )

_________________________________

Step (3)

It's time to put the the coordinates in the above equation :

[tex]slope = \frac{ - 23 - ( - 3)}{ - 18 - ( - 3)} \\ [/tex]

[tex]slope = \frac{ - 23 + 3}{ - 18 + 3 } \\ [/tex]

[tex]slope = \frac{ - 20}{ - 15} \\ [/tex]

Negatives simplified :

[tex]slope = \frac{20}{15} \\ [/tex]

The face and denominator are reduced to five :

[tex]slope = \frac{4}{3} \\ [/tex]

_________________________________

And we're done.

Thanks for watching buddy good luck.

What is the equation of a line PARALLEL to y = 1/3x – 4 that passes through (9, 8)?

Answers

Answer:

[tex]y=\frac{1}{3} x+5[/tex]

Step-by-step explanation:

We know that since the equation of the line that we need to find has to be parallel, it must have the same slope. Also, the slope-intercept formula is:

[tex]y=mx+b[/tex]

Plugging in the values we know:

[tex]8=\frac{1}{3} (9)+b[/tex]

We solve for [tex]b[/tex] and get:

[tex]b=5[/tex].

So, the equation of our new line must be:

[tex]y=\frac{1}{3} x+5[/tex]
